Answer:

#9 24 T-Shirts for $168

#10 the diffirence between 30 T-Shirts and 9 T-Shirts is 147

Step-by-step explanation:

so to get the cost (c) for 1 T-Shirt you need to divide 147 by 21

147 ÷ 21 = 7

so c=7

10x7=70

70x3=210

30x7=210

so 30 shirts cost $210

and 9x7=63

so now it is time to do the rest of the math.

210

-63

147
