ITEM 2
At the beginning of term two, Kumasi secondary school's administration
faced a pressing issue: - a shortage of dormitory space for students. To
address this sleeping accommodation deficit, the school's management
developed a plan to construct new hostels with a rectangular design,
where the length is √3 times the width, resulting in a perimeter of
(14+6√3) units. To fund this project, the administration required a 97%
collection rate of school fees from students.By the end of the first week of
the term, two-thirds of the student body had settled their fees. In the
subsequent week, an additional 100 students paid their fees, resulting in a
significant increase in the proportion of students who had paid their fees,
reaching three-quarters of the total student population.
TASK
a) Guide the school management to ascertain the land area, ensuring a
surd form solution with rationalized numerals and simplified radicals.
b) Ascertain the precise number of students in the school.
c) Guide the school administration on whether the construction can be
undertaken, with supporting reasons.
ITEM 3
Mr. Alex, a seasoned bus driver at the New Taxi Park, was hired to
transport 377 students for a field trip from Mukono to Entebbe. When the
geography teacher inquired about the best route, Mr. Alex expertly
outlined two alternative routes, ensuring a smooth and informed journey
from Mukono to Entebbe. The shorter route takes 2 hours and 26 minutes
to complete, with the driver maintaining an average speed of 54km/h for
the first x kilometers and 37.5km/h for the last y kilometers. The longer
route, which is 5km longer than the shorter route, takes the driver 2 hours
and 12 minutes to complete at an average speed of 60km/h. The driver
also charges a fare of Shs 1000 per student per kilometer.
TASK
a) Create two mathematical models involving x and y which can be used
to help in the analysis of the two routes.
b) Help Mr. Alex by revealing the hidden values of x and y from the
equations in (a) above.
c) Guide the geography teacher on the best route, highlighting the
benefits of your proposed option.
ITEM 4
Garden City Shopping Mall in Kampala is experiencing a massive turnout
of customers, leading to a critical shortage of parking spaces. To address
this challenge, the mall's management has planned an innovative solution:
a triangular rooftop parking design, exclusively designed for compact
cars, each spanning an area of 0.2 square units, to cater for the growing
demand of space. The parking area is bounded by the following
constraints; x+ y< 3 , x− y+ 3 ≥ 0, and y + 1 ≥ 0. To capitalize on the high
demand for parking, the mall plans to impose a parking fee of Shs 2500
per vehicle, with calculations indicating that on peak days, the cars will
occupy a total area of 12.4 square units, yielding a significant income
source.

ITEM 9
To enhance the yields of Rice, Beans, Sugarcane, and Peas in Iganga
district, the Ministry of Agriculture's Farmer Training and Capacity
Building program conducted a survey, yielding the following findings;
Among the 80 rice farmers surveyed, 45 also grow beans, 60 cultivate
sugarcane, and 5 focus solely on peas and rice. Additionally, 5 farmers
dedicate their land solely to rice. The number of farmers who grow beans,
sugarcane, peas, and rice is equal to those who grow peas,
sugarcane, and rice. Moreover, the farmers who cultivate rice, and
sugarcane only are equal in number to those who grow rice, peas, and
beans, and are 5 fewer than those who grow all four crops.
The ministry plans to provide support to these farmers as follows:
• A farmer who cultivates all four crops (beans, sugarcane, peas, and rice) will
receive a package consisting of 4 tractors and a cash grant of UGX 3,000,000.
• One who plants only three crops will receive 3 tractors and UGX 2,000,000.
• A farmer who grows two crops only will receive 2 tractors and UGX
1,500,000.
• For a single crop will receive 1 tractor and UGX 1,000,000.
This support aims to motivate farmers to diversify their crops and boost their
productivity.
The ministry needs to calculate the total cost of tractors for farmers,
based on the number of tractors needed for each group, with each tractor
costing UGX 68,000,000.
