Answer:
- Item from shelf A cost $5.41 and items from shelf B cost $4.89
Step-by-step explanation:
x represents an item form shelf A, y represents an item from shelf B.
The equations are:
Solve by elimination.
Multiply the first equation by 2 and the second one by 3, then subtract the first equation form the second:
- 6x + 15y - 6x - 4y = 96 - 52
- 9y = 44
- y = 44/9 = 4.89 (rounded)
Find the value of x:
- 3x + 2*4.89 = 26
- 3x = 26 - 9.78
- 3x = 16.22
- x = 16.22/3
- x = 5.41 (rounded)
