If Mary exchanges $400 from dollars to pounds and the exchange rate is 60 pounds for every $100, how many pounds will she get?

240 pounds

Step-by-step explanation:

60x4

She will get 240 pounds

Step-by-step explanation:

She gets 60 pounds per each $100, and she has 4 $100.

60 + 60 + 60 + 60, (four 60's) is how much she will get.

Or you can just do 4x60.
