Hello! :)
![\large\boxed{\text{70 seconds}}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B%5Ctext%7B70%20seconds%7D%7D)
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:
![\frac{2 shirts}{28 seconds} = \frac{5 shirts}{xseconds}](https://tex.z-dn.net/?f=%5Cfrac%7B2%20shirts%7D%7B28%20seconds%7D%20%20%3D%20%5Cfrac%7B5%20shirts%7D%7Bxseconds%7D)
Cross multiply and simplify:
![2 * x = 5 * 28\\\\2x = 140\\\\x = 70 sec](https://tex.z-dn.net/?f=2%20%2A%20x%20%3D%205%20%2A%2028%5C%5C%5C%5C2x%20%3D%20140%5C%5C%5C%5Cx%20%3D%2070%20sec)
Therefore, he needs 70 seconds to fold 5 shirts.
The answer is B.98
180-122=58
58+24=82
180-82=98
Hope it helped
