Question

Ira bought a tennis racquet that cost $112. The sales tax rate is 9 percent. What is the total amount that she paid?
$121
$122.08
$122.80

Answer 1

So she paid the 112 PLUS whatever 9 percent of that 112 is..

\[\large Total = 112 + (0.09 \times 112) = ?\]

Answer 2

im tryna put it in the calculator but it doesnt make any sense

Answer 3

do you know how to find percentage?

Answer 4

no not at all thats what has me confused

Answer 5

okay so to find the percentage of something, you need to divide the percentage by the number they give you so 9% translates into 0.09 in decimal form

Answer 6

first find tax =(9*112)/100
then total cost =112+tax

Answer 7

\[0.09/112\] which gives you some number then you multiply that result by 100 and then you add the final result to 112

Answer 8

but if it comes back to 112 as a result what would i divide or times it by the ???

Answer 9

Answer 10

what?.... what did you get as your final result?

Answer 11

0.000803571428571

Answer 12

wow okay umm you must've done some thing wrong
step 1 convert 9% into a decimal which would be 0.09
step 2 divide 0.09 with 112 to get 0.075

Answer 13

are you with me so far?

Answer 14

an i did divide an im getting the same answer

Answer 15

why would you divide after this? you're done dividing after step 2

Answer 16

Where are you getting that 0.075 from?

Step 1) Find the tax...9 percent = 0.09....multiply that 0.09 * 112 = some number

That is your tax

Step 2) Add the tax to the original amount to find the total cost
