A phone sells for $245. It is now on sale for 1/5 of the original price. April has a coupon for an extra 10% off sale price. How much less than the original price will April pay for the phone.

April will pay $68.6 lesser than the original price.

Step-by-step explanation:

The phone sells for $245. It is now on sale for 1/5 of the original price. It means that the amount that was taken off the original price is

1/5 × 245 = $49

The sale price of the phone would be

245 - 49 = $196

April has a coupon for an extra 10% off sale price. It means that the amount he would save off the sale price is

10/100 × 196 = $19.6

The final price that April will pay for the phone is

196 - 19.6 = $176.4

The difference between the original price and price that April will pay for the phone is

245 - 176.4 = $68.6
