During a sale, all items in a departmental store are given 10% discount. A dress costs $ 83.25 during the sale. Find the original price of the dress before the sale.

Original price =$ 92.5

Step-by-step explanation:

Let the original price of the dress be $x.

Since 10% discount is given on all items during sale in the departmental store.

Therefore,

Original price - 10% discount of original price = $ 83.25

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
