Set up an equation to solve.
$8.50x (since it is the rate of change) + $12 (flat fee) = total money earned (or y). In this case, we have the total, amount, and are looking for x. Plug $139.50 into the equation.
$8.50x + $12 = $139.50
Now, solve for x.
$8.50x + $12-12 = $139.50-12 > <em>$8.50x = $127.5</em>
$8.50/8.50x = $127.5/8.50 > <em>x = 15</em>
So, the correct answer is <u>D. Olivia babysat for 15 hours.</u>

Hello! The tax rate is 8%. To find the total price paid for the television, let's first add 1 to the percentage in decimal form. 8% is 0.08. 1 + 0.08 is 1.08. Multiply that number by 330 to get 356.4. There. May pays a total of $356.40 for the television.
Note: When it comes to skipping straight to the total amount with tax, always add 1 to the tax rate (tax rate should be in decimal form). This will take you straight to the answer and save you some time and paper.
