Question

Suppose you bought 5 turkey and 7 ham

sandwiches for $38.50. The next day, you buy 6
ham and 4 turkey sandwiches for $32,00. How
much does each type of sandwich cost?

Answer 1

turkey: $3.50

ham: $3

Explanation:

Use system of equations:

turkey-x ham-y

5x+7y=38.5

4x+6y=32

multiply by 4 on equation 1 and multiply by 5 on equation 2

20x+28y=154

20x+30y=160

-2y=-6

y=3 ham is $3

5x+7(3)=38.5

5x=38.5-21

5x=17.5

x=3.5 turkey is $3.50
