A garment company makes two types of woolen sweaters and can produce a max of 700 sweaters per week. Each sweater of the first type requires 2 pounds of green wool and 4 pounds of pink wool to produce a single sweater. The second type of sweater requires 4 pounds of green wool and 3 pounds of pink wool. The profit earned the first type of sweater is $5 and on the second type $7 . The company has 50 ounds of green wool and 80 pound of pink wool.
Write a system of inequalities to represent the number of sweaters of the first type and the number of sweaters of the second type that can be produced.

let the number of sweaters of the first type be x
let the number of sweaters of the second type by y
x+y ≤ 700  total sweaters
2x + 4y ≤ 50  green wook
4x + 3y ≤ 80  pink wool
Profit = 5x + 7y

That depends upon the interest rate. Balance of what? How much is borrowed?
Did you ask the original question, or are you just causing a disruption?
