Monica paid sales tax of $2.40 when she bought a new bike helmet. If the sales tax rate was 6%, how much did the store charge for the bike helmet before tax?
I don't understand what is the answer?
.06 * h = 2.40
solve for h
To find the amount that Monica paid for the bike helmet before tax, we need to reverse calculate the amount of sales tax she paid. We are given that the sales tax rate is 6% and the amount of sales tax she paid is $2.40.
Let the cost of the bike helmet before tax be represented by x.
To find the amount before tax, we need to solve the equation:
Sales tax amount = Sales tax rate * Cost before tax
$2.40 = 6% * x
To solve for x, first convert 6% to decimal form:
6% = 6/100 = 0.06
Now we can rewrite the equation:
$2.40 = 0.06x
To isolate x, divide both sides of the equation by 0.06:
$2.40 / 0.06 = x
40 = x
Therefore, the store charged Monica $40 for the bike helmet before tax.
