neeed pl1. at the grocery store checkout, you watch at the register as it rings up your purchases and coupons. the prices are as follows: $2.95 $1.19 $4.61 $1.74 $3.04 $8.83 $1.16 − $0.75 (coupon) − $1.00 (coupon) the register gives your total bill as $21.77. (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.

Hello there, here are the correct answers to your question!

a) The estimated value of the bill would be $24.

b) Yes, the total on the register is reasonable. The estimate is $24, and after subtracting the estimated coupon amount of $2, you get $22, which is very close to $21.77

Here is the work I did to get your answers:

part a:

$2.95 $1.19 $4.61 $1.74 $3.04 $8.83 $1.16 − $0.75 − $1.00

Round to the nearest dollaer amount.

$3 $1 $5 $2 $3 $9 $1 - $1 - $1

Add the values of your purchases (excluding the coupons)

$3 + $1 + $5 + $2 + $3 + $9 + $1

$4 + $7 + $3 + $10

$4 + $20

$24

Part b:

Together, the coupon gives you $-2 off, so subtract $2 from $24

$24 - 2 = $22

So yes, the total is reasonable since $22 is very close to $21.77.

I hope this helps, and have a great day! Please don't hesitate to ask if you need more help with this specific question!
