amy paid $67.65 for a pair of running shoes during a 30% of sale. what was the regular price?
0.7x = 67.65
x = ?
no idea
0.7x = 67.65
Divide both sides of the equation by 0.7.
What is 67.65 divided by 0.7?
amy paid $67.65 for a pair of running shoes during a 30% of sale
Regular price = 67.65 * 30/100 + 67.65
= 20.295 + 67.65
= $ 87.945
To find the regular price of the running shoes, we need to reverse the 30% discount that Amy received.
Step 1: Calculate the 30% discount amount
Discount amount = 30% of the regular price
Since we don't have the regular price, let's assume it as "x".
Discount amount = 0.30 * x
Step 2: Calculate the sale price
Sale price = Regular price - Discount amount
In this case, Amy paid $67.65, so:
Sale price = $67.65
Step 3: Set up an equation to solve for the regular price
$67.65 = x - 0.30x
Step 4: Combine like terms
$67.65 = 0.70x
Step 5: Solve for x by dividing both sides by 0.70
x = $67.65 / 0.70
Step 6: Calculate the regular price
x = $96.64
Therefore, the regular price of the running shoes was $96.64.
