Answer 1

Cost of chip cookies = $17.5

Cost of ginger cookies = $19.5

Explanation:

Assume;

Cost of chip cookies = c

Cost of ginger cookies = g

So,

Maya's sales = 8c + 12g = 374 .....Eq1

Carlo's sales = 2c + 4g = 113 .......Eq2

4 x eq2

So

8c + 16g = 452......Eq3

Eq 3 - Eq 1

4g = 78

g = 19.5

and

c = 17.5

Cost of chip cookies = $17.5

Cost of ginger cookies = $19.5
