Ineed asap rose bought a new hat when she was on vacation. the following formula describes the total amount rose paid t = c + cb = total cost rose paid for the hat = price of hat = sales tax (percent)i f the hat cost $975 and the sales tax was 5%, how much did rose pay for the hat?

Rose paid $1,023.75 for the hat.

Step-by-step explanation:

Hi, to answer this question we have to substitute c=975 and b =5/100 in the equation given.

t = c + cb

Where  

t = total cost

c = price of the hat

b = sale tax percent (in decimal form, dividing the percentage by 100)

Replacing with the values given and solving for t:

t = 975 + (975 x [5/100])

t = 975 + (975 x 0.05)

t = 975+48.75

t= $1,023.75

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
