He wants to buy a maximum of 80 crates of type A and at least 10 crates of type B. Letting x represent the number of crates of type A and y the number of crates of type B;
(a) Write down all the inequalities which represent the above information.
(b) Represent the inequalities in (a) above on the graph provided.
The profit from the sale of a crate of type A is kshs. 60, while that of type B is kshs. 40. Find the number of crates he should buy to maximize his profit.
(c) Find the profit.

a)x + y = 100
x = 2y
x = 80
y = 10

Type A = 80 crates
Type B = 20 crates

c)Profit = (80 × 60) + (20 × 40)
= shs. 5600
