Question

At an ice cream shop, the cost of 4 milkshakes and 2 ice cream sundaes is $23.50. The cost of 8 milkshakes and 6 ice cream sundaes is $56.50.

What is the price of a milkshake?
What is the price of an ice cream sundae?

Answer 1

If I had to take a guess I'd say the price of the milkshakes is $4.50 and the price of the sundaes are $2.75 but I'm not 100% sure.

Answer 2

Explanation:

8m + 6i = 56.50

4m + 2i = 23.50

8m + 6i = 56.50

-8m - 4i =-47.00

2i = 9.50

i = $4.75 ice cream sundae

4m + 2(4.75) = 23.50

4m + 9.50 = 23.50

4m = 14

m = 3.50 milkshake
