49x3= 147 so 10 reduction will make tim spend 137. 49x5= 245 so 20 reduction will make Craig spend 225. 225-147= 78 so Craig spends 78£ more than tim. All the offers state “X or Y” meaning it’s one or the other hence the ‘or’. Atleast that’s my interpretation of it.

Hello! Can someone help with this question?
IgorC [24]

Hello! :)

\large\boxed{\text{70 seconds}}

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}

Cross multiply and simplify:

2 * x = 5 * 28\\\\2x = 140\\\\x = 70 sec

Therefore, he needs 70 seconds to fold 5 shirts.
