At an ice cream store, a family ordered 1 banana split and 2 hot fudge sundaes, paying a total of $11 for their order. The next customer ordered 4 banana splits and 3 hot fudge sundaes and paid $29. How much does each item cost?
1 answer:
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
