Answer:
3x-8y+40z
Step-by-step explanation:
Answer:
x = $0.50
y= $0.75
Step-by-step explanation:
1. Multiply the equations to have the same coefficients
5(6x + 6y = 7.5) → 30x + 30y = 37.5
3(10x + 5y = 8.75) → 30x + 15y = 26.25
2. Subtract the equations
30x + 30y = 37.5
<u>- 30x + 15y = 26.25</u>
15y = 11.25
3. Solve for y by dividing both sides by 15
y = 0.75
4. Plug in 0.75 for y into one of the equations
6x + 6(0.75) = 7.5
5. Simplify
6x + 4.5 = 7.5
6. Solve for x
6x = 3
x = 0.5
The large box is less expensive per ounce.
large box small box
cost 4.16 2.38
content 32oz 14oz
cost/oz 0.13 0.17
*4.16/32 *2.38/14
The large box is less expensive than the small box. The large box is cheaper by 0.04 per ounce.
