Hey there!
The 3 games cost $14.99 each, so multiply to find the cost of the three combined without the tax (the subtotal).
14.99 × 3 = 44.97
To find the amount of tax she will have to pay, we must find 7% of 44.97, the price without the tax added to it (the subtotal).
100% = 1.0
7% = 0.07
Multiply 44.97 by 0.07 for the amount of tax.
44.97 × 0.07 = 3.1479
Add the tax to the cost of the games without tax (subtotal).
44.97 + 3.1479 = 48.1179
Round the amount to the nearest cent. The thousandths place is 7, so it gets rounded up.
The total she has to pay for the games is $48.12.
Hope this helps!
