Question

monica paid sales tax of $1.50 when she bought a new bike helmet.If the sales tax rate was 5% ,how. much did the store charge 6 grade answer key

Answer 1

To find the total from the percent part you have, you divide the part by the percentage.
1.50÷0.05=30
The total is $30
The total the store charged, including sales tax, is $31.50.

Answer 2

In order to obtain the total amount that Monica was charged you should follow some steps.

How much was the net price? You can obtain this value either by clearing the x:

X * 5% = $1.50

X = $1.50 / 5%

Or by using simple rule of three:

If 5% is $1.50

Then 100% is X

So you obtain = $30

Now you just need to sum The net prices and the taxes

Net + tax = Total Charge

$30 + $1.5 = $31.5
