Good afternoon!I'm homeschooled so they only give us workbooks and ect. They explain how to do the problems but it confuses me. Here is 1 out of the 5 q's I don't get.
A printer is on sale for $129.99. This is 25% off the regular price. what is the regular price? Solve each problem by writing an equation.
if it's 25% off, then 129.99 is 75% of the regular price
129.99 = .75p
p = 129.99/.75 = 173.32
how did you get 173.32?
173.32 . Steve even worked it out.
173.32. me and my dad did it at the same time.
Good afternoon! I can help you understand how to solve this problem.
To find the regular price of the printer, we need to set up an equation using the given information. Let's call the regular price of the printer "x".
The problem states that the printer is on sale for $129.99, which is 25% off the regular price. To calculate the sale price, we need to subtract the discount from the regular price:
Sale price = Regular price - Discount
The discount is 25% of the regular price. To calculate this, we can multiply the regular price by 25% (or 0.25):
Discount = 0.25 * Regular price
Now we can substitute the values into our equation:
$129.99 = Regular price - 0.25 * Regular price
To simplify further, we can factor out the regular price:
$129.99 = (1 - 0.25) * Regular price
Simplifying the equation:
$129.99 = 0.75 * Regular price
To isolate the regular price, we divide both sides of the equation by 0.75:
Regular price = $129.99 / 0.75
Now we can solve for the regular price using a calculator:
Regular price ≈ $173.32
Therefore, the regular price of the printer is approximately $173.32.
Remember to always double-check your work and consider rounding if necessary. Let me know if you have any further questions!
