Answer:
cupcake = $4.99
ice-cream = $2.99
Doughnut = $1.19
Explanation:
3 cupcakes = $14.97
1 cupcake = 14.97 ÷ 3 = $4.99
1 doughnut + 2 ice-creams = 7.17 ------------ [ 1 ]
[1] x 2 : 2 doughnuts + 4 ice-creams = 14.34 ------------ [ 1A ]
2 doughnuts + 1 ice-cream = 5.37------------ [ 2 ]
[1A] - [2]:
3 ice-creams = 8.97
1 ice-cream = 8.97 ÷ 3 = $2.99
Sub 1 ice-cream = $2.99 into [1]
1 doughnut + 2(2.99) = 7.17
1 doughnut + 5.98 = 7.17
1 doughnut = 7.17 - 5.98 = $1.19
