Answer:
43 1/3 minutes to iron 10 shirts
Step-by-step explanation:
Number of shirts : Time taken
3 shirts : 13 minutes
10 shirts : x minutes
3 / 13 = 10 / x
Cross product
3 * x = 13 * 10
3x = 130
Divide both sides by 3
3x / 3 = 130 / 3
x = 43 1/3 minutes
x = 43 minutes 20 seconds
It will take 43 minutes 20 seconds to iron 10 shirts
I believe it is 84. good luck.
