Final answer:
April will pay $69 less than the original price for the phone.
Step-by-step explanation:
To find out how much April will pay for the phone, we need to calculate the discount and the final price after applying the coupon. The phone is on sale for 1 over 5 off the original price, which is equivalent to a 20% discount (100% - 20% = 80%). So, the sale price of the phone is $245 x 0.8 = $196.
Next, April has a coupon for an extra 10% off the sale price. To calculate the reduced price after applying the coupon, we multiply the sale price by 0.9 (100% - 10% = 90%). So, April will pay $196 x 0.9 = $176.40.
To find out how much less than the original price April will pay, we subtract the final price from the original price: $245 - $176.40 = $68.60. Rounding to the nearest dollar, April will pay $69 less than the original price for the phone.
