A store is having a 20%-off sale on all merchandise.
lyudmila [28]
This is easy . There is a 20 percent discount which means now it’s only (100-20%) discount.
This is 80% discount.
Money saved is equal to 100-80%
=20%
And that 20% is equal to 13$ as per the passage.
So now we need to calculate 1 percent of the item without discount .
This is equal to 13/20
This is equal to .65
Now to find the original price you will need to multiply .65 to 100 this is equal to 65$.

Virty [35]

Answer:

y = 36x

Step-by-step explanation:

Given that x and y vary directly then the equation relating the is

y = kx ← k is the constant of variation

To find k use the condition x = \frac{1}{3}, y = 12, then

k = \frac{y}{x} = \frac{12}{\frac{1}{3} } = 12 × 3 = 36

y = 36x ← equation of variation
