kim sold 13 apple pies and 12 blackberry pies for $345 jasmine sold 5 apple pies and 12 blackberry pies for $273 whats the cost per apple and blackberry pie

Answer 1

13a + 12b = 345

5a + 12b = 273

subtract

8a = 72

a = $9 per apple pie

b = 273-45/12 = 228/12 = $19 per blueberry pie

13(9) + 12(19)

= 117 + 228

= 345

5(9) +12(19)

= 45 + 228

= 273
