In a sale, normal prices are reduced by 17%. The normal price of a washing machine is reduced by £42.50

Work out the sale price of the washing machine.

The sale price of the washing machine is £207.50.

Step-by-step explanation:

Percentages

To find a percentage of a given number, the procedure is multiplying the percentage by the number and divide by 100.

Suppose the normal price of the washing machine was x before the discount. The discount is:

17% of x = 17/100 * x = 0.17x

This discount is given as £42.50, thus:

0.17x = £42.50

Solving:

x = £42.50/0.17

x = £250

The sale price is:

£250 - £42.50 = £207.50

The sale price of the washing machine is £207.50.

the answer is 40.
