It will take at least 15 weeks
Step-by-step explanation:
12w+31 ≥ 205
Subtract 31 from each side
12w+31-31 ≥ 205-31
12w ≥ 174
Divide each side by 12

w ≥ 14.5
Rounding up to the nearest integer
w ≥ 15
It will take at least 15 weeks
Hello! :)

Use a proportion to find how many seconds are needed to fold 5 shirts.
We are given that he takes 28 seconds to fold 2 shirts:
28 sec : 2 shirts
We are not given the amount of time needed for 5 shirts, which we need to solve:
x seconds : 5 shirts
Express in a fraction:

Cross multiply and simplify:

Therefore, he needs 70 seconds to fold 5 shirts.
