(a) Round each price and coupon to the nearest dollar and then estimate the total amount of the bill. (b) Using your estimate, determine whether the total on the register is reasonable. Justify your answer

Answer 1

First of all, you need to round the decimal numbers (round the cents )
So,
2.95 = 3
1.19 = 1
4.61 = 5
1.74 = 2
3.04 = 3
8.83 = 9
1.16 = 1

The aggregate of all them = 24

Now , subtract the coupon amount.
24-(1 + 1)
= 22

So, the total amount of bill is 22.
