Answer: April will pay $68.6 lesser than the original price.
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
