Answer:
$5 and $3
Step-by-step explanation:
Cost of banana split = b
Cost of hot fudge sundae = s
<u>From the first equation we get: </u>
<u>Replacing in the second equation:</u>
- 4(11 - 2s) + 3s = 29
- 44 - 8s + 3s = 29
- 44 - 29 = 5s
- 15 = 5s
- s = 15/5
- s = 3
Then
- b = 11 - 2*3 = 11 - 6 = 5
So banana split costs $5 and hot fudge sundae costs $3
