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.
Second Discount
20% off means we paid 80%. We know we paid $328 of some price.
[tex]\frac{80}{100} =\frac{328}{y} \\[/tex]
I can now cross-multiply by multiplying numerator and denominator from each ratio.
[tex]80y=100(328)\\80y=32800[/tex]
I now solve for y by dividing by 80.
[tex]\frac{80y}{80} =\frac{32800}{80}[/tex]
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%.
[tex]\frac{82}{100}=\frac{410}{y}[/tex]
I can now cross-multiply by multiplying numerator and denominator from each ratio.
[tex]82y=100(410)\\82y=41000[/tex]
I now solve for y by dividing by 82.
[tex]\frac{82y}{82} =\frac{41000}{82}[/tex]
y=500
The original price was $500.
