arista found a sale on skates. she got 1/5 off the regular price of $34.50. What was the sale price of her skates?
34.50 * 0.8 = ?
To find the sale price of Arista's skates, we need to calculate the discount amount and subtract it from the regular price.
First, let's find the discount amount. Arista received 1/5 off the regular price, which is equivalent to a discount factor of 1 - 1/5 = 4/5.
Next, we calculate the discount amount by multiplying the regular price by the discount factor:
Discount amount = Regular price * Discount factor
Discount amount = $34.50 * 4/5
Discount amount = $27.60
Finally, we can calculate the sale price by subtracting the discount amount from the regular price:
Sale price = Regular price - Discount amount
Sale price = $34.50 - $27.60
Sale price = $6.90
Therefore, the sale price of Arista's skates is $6.90.
