Victoria wants to purchase a skateboard. she has $125 to spend. she finds one that regularly sells for $139.99 and is on sale for 15% off. sales tax is 7%. victoria says that she has enough money to buy the skateboard. is she correct? explain

Well, to see if she can afford the skateboard, start by finding the discount and then finding the sales tax of that.

To find the discount, first find 15% of $139.99 and then subtract it since that's how much you're getting off.

Remember: to find percentage, convert the percentage into a decimal by dividing it by 100, and then multiplying it by what you're finding a percentage of.

15% ÷ 100 = 0.15

$139.99 x 0.15 = 20.9985, which can be rounded up to $21.

$139.99 - 21 = 118.99.

Now that we have the discount, we find the sales tax, which can be found the same way as the discount, but we add it to the total instead fo subtracting it.

7% ÷  100 = 0.07

0.07 x 118.99 8.3293 or  $8.33

118.99 + 8.33 = 127.32

This is the final total of how much the skateboard would cost.

So:

No, she would not have enough money to buy the skateboard. With the discount alone, she could afford it, since $118 falls in her budget range, but with the added tax, it's 13 dollars over and she cannot afford the skateboard.
