Answer: 0.04 per pound
Step-by-step explanation:
A 5 pound bag of apples costs 4.50.
The unit price will be 4.50 divided by 5 which will be:
4.50 ÷ 5 = 0.9
The unit price is 0.9 per pound
A 8 pound bag of the same type of apples costs 7.52.
The unit price will be 7.52 divided by 8 which will give:
7.52 ÷ 8 = 0.94
The unit price is 0.94 per pound
The difference in the unit prices will be the subtraction of 0.90 from 0.94.
0.94 - 0.90 = 0.04
The difference in the unit prices is 0.04 per pound.
-2x + 15y = -24
2x + 9y = 24
Adding to eliminate x:-
24y = 0
y = 0
Substitute for y in the first equation:-
-2x + 15(0) = -24
-2x = -24
x = -24/-2 = 12
Solution is x = 12 , y = 0
