Question

Francis can buy 7 shirts for $42 or 8 shirts for $48. How much will she pay for nine?

Answer 1

Answer: $54

Step-by-step explanation:

if we divide 42 by 7, or we divide 48 by 8, we can see that it is 6. so, one shirt costs $6. then, we just multiply 9 (the amount of shirts) by 6 (the cost of a shirt), and we get 54.
