Write your answer in £.

A) Isaac should get £ 10.75 in change.

B) The price of the e-scooter in the sale is £ 366.3.

Step-by-step explanation:

A) Given that Isaac buys 17 anti-pollution masks for £ 5.25 each, and he pays with five £ 20 notes, to determine how much change Isaac should get, the following calculation must be performed:

(20 x 5) - (17 x 5.25) = X

100 - 89.25 = X

10.75 = X

So Isaac should get £ 10.75 in change.

B) Given that the normal price of an e-scooter is £ 370 and, in a sale, there is 1 off the normal price of the e-scooter, to determine the price of the e-scooter in the sale the following calculation must be performed:

370 - (370 x 0.01) = X

370 - 3.7 = X

366.3 = X

Thus, the price of the e-scooter in the sale is £ 366.3.
