Answer:
Step-by-step explanation:
7.50x + 6y ≤ 92. AND. x + y ≥ 20
The answer is 360 because if u do this 20×36 and the 1/2 it u get this 360 20×36 is 720 and then 2÷720 u get 360
Answer:
y = 
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 5 when x = 6
k =
= 
y =
x ← equation of variation
When x = 5, then
y =
× 5 = 
Answer:
126.25
Step-by-step explanation:
take 8.75 and multiply by 8 =70
take 8.75+2.50=11.25
11.25x5=56.25
56.25+70=126.25
