Question

Yolanda sold t-shirts at a festival and made a profit of $71. She made $4 for each t-shirt she sold. Her total expenses were $25. How many t-shirts did she sell?

Answer 1

71= 4x -25

96= 4x

x= 96/4 = 24

she sold 24 T shirts

Ax+B= C

4x +(-25) = 71

4(24)-25 =71

96-25 = 71

A=24

B=-25

C=71
