Josh bought 3 bottles of grape juice and 5 bottles of water for a total of $14.50. Mary bought 2 bottles
1 answer:
Answer:
- Bottle of water = $2
- Bottle of grape juice = $1.50
Step-by-step explanation:
<u>Equations:</u>
- 3g + 5w = 14.50
- 2g + 3w = 9.00
<u>Subtract the 3 times the second equation from the twice the first:</u>
- 2*(3g + 5w) - 3(2g + 3w) = 2*14.50 - 3*9.00
- 6g + 10w - 6g - 9w = 29 - 27
- w = 2
<u>Then, finding g:</u>
- 3g + 2*5= 14.50
- 3g = 14.50 - 10
- 3g = 4.5
- g = 1.50
