Answer:
- Iced tea is $4.50 per gallon
- Lemonade is $4.75 per gallon
Step-by-step explanation:
<u>Price</u>:
- Iced tea = x, lemonade = y
<u>Equations</u>:
- 2x + 3y = 23.25
- 5x + 4y = 41.50
<u>Multiply the first equation by 5 and the second equation by 2 and subtract to eliminate x:</u>
- 5(2x + 3y) - 2(5x + 4y) = 5(23.25) - 2(41.50)
- 10x + 15y - 10x - 8y = 33.25
- 7y = 33.25
- y = 33.25/7
- y = 4.75
<u>Use the first equation to find x:</u>
- 2x + 3(4.75) = 23.25
- 2x = 23.25 - 14.25
- 2x = 9
- x = 9/2
- x = 4.50
Iced tea costs $4.50 per gallon
Lemonade costs $4.75 per gallon
