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.

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.

Step-by-step 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

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.

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
