The first discount on a camera was 18%. the second discount was 20%. after these two discounts the price was $328. what was the original price?

$500

Step-by-step explanation:

We can find the original price of the camera through a proportion. A proportion is an equation where two ratios or fractions are equal. The ratios or fractions compare like quantities.

Second Discount

20% off means we paid 80%. We know we paid $328 of some price.

I can now cross-multiply by multiplying numerator and denominator from each ratio.

I now solve for y by dividing by 80.

y=410

The price after the first discount was $410.

First Discount

We will repeat the steps above with $410. 18% off means we paid 82%.

I can now cross-multiply by multiplying numerator and denominator from each ratio.

I now solve for y by dividing by 82.

y=500

The original price was $500.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
