HELPPP I NEED THE ANSWER FAST PLEASEEE Shirley is buying a $27 scarf. If the sales tax is 7.25% and she hands the cashier $30, how much change will she get back? YOU GET 86 POINTS FOR ANSWERING THIS BECAUSE I HAVE A C- IN MATH

Answers

Hi, I think the answer should be $4.26

7.25% × $24 = $1.74

$24 +1.74 = $25.74

Change is the difference between the amount tendered and this total amount:

$30.00 -25.74 = $4.26

Answer: $1.04

Step-by-step explanation:

Cost of scarf = $27

sales tax = 7.25% of 27 = $1.9575 (round to $1.96)

Total cost = 27 + 1.96 = $28.96

$30.00 - $28.96 = $1.04 change

The diameter of a tire is 2.5 ft. Use this measurement to answer parts a and b. Please show all work.

A. Find the circumference of the tire.
B. About how many times will the tire have to rotate to travel 1 mile? (1 mile = 5,280 ft)

Answers


You meed to subtract and divide

Answer:

the circumference is 5, since the diameter is half, so you have to double 2.5 to get 5.    2.5 + 2.5 = 5

if the tire rotates 1 time and gains 5 feet, we have to divide 5 from 5,280. So...

5,280 ÷ 5 = 1056

it rotates 1056 times to get to 1 mile!
