Question

1. At the bookstore checkout, you watch as the register rings up your purchases and coupons. The prices were as follows:

$1.85
$8.56
$6.30
$2.73
$5.25
$4.09
$7.95
– $0.85 (coupon)
– $2.10 (coupon)

The register gives your total bill as $41.44. Estimate the total amount of the bill, by rounding
each value to the nearest dollar, and use your answer to determine whether the total on the register is reasonable. Answer:

Answer 1

Answer: No , it is not reasonable as the total amount is sum upto $34 but in register the amount of bill is shown is greater than the original bill amount.

Explanation:

Since we have given that

The prices rounded off to the nearest dollar were as follows:

$1.85 → $2

$8.56 → $9

$6.30 → $6

$2.73 → $3

$5.25 → $5

$4.09 → $4

$7.95 → $8

– $0.85 (coupon) → $1

– $2.10 (coupon) → $2

So, total amount will be

`2+9+6+3+5+4+8-1-2=\$34`

But the value in the register gives total bill as $41.44

So, it is not reasonable as the total amount is sum upto $34 but in register the amount of bill is shown is greater than the original bill amount.
