Answer:
$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.

20% off means we paid 80%. We know we paid $328 of some price.
![\frac{80}{100} =\frac{328}{y} \\](https://tex.z-dn.net/?f=%5Cfrac%7B80%7D%7B100%7D%20%3D%5Cfrac%7B328%7D%7By%7D%20%5C%5C)
I can now cross-multiply by multiplying numerator and denominator from each ratio.
![80y=100(328)\\80y=32800](https://tex.z-dn.net/?f=80y%3D100%28328%29%5C%5C80y%3D32800)
I now solve for y by dividing by 80.
![\frac{80y}{80} =\frac{32800}{80}](https://tex.z-dn.net/?f=%5Cfrac%7B80y%7D%7B80%7D%20%3D%5Cfrac%7B32800%7D%7B80%7D)
y=410
The price after the first discount was $410.

We will repeat the steps above with $410. 18% off means we paid 82%.
![\frac{82}{100}=\frac{410}{y}](https://tex.z-dn.net/?f=%5Cfrac%7B82%7D%7B100%7D%3D%5Cfrac%7B410%7D%7By%7D)
I can now cross-multiply by multiplying numerator and denominator from each ratio.
![82y=100(410)\\82y=41000](https://tex.z-dn.net/?f=82y%3D100%28410%29%5C%5C82y%3D41000)
I now solve for y by dividing by 82.
![\frac{82y}{82} =\frac{41000}{82}](https://tex.z-dn.net/?f=%5Cfrac%7B82y%7D%7B82%7D%20%3D%5Cfrac%7B41000%7D%7B82%7D)
y=500
The original price was $500.
