SOLUTION

When Leo imported a certain item, he paid a 7 percent import tax on the portion of the total value of the item in excess of $1,000. If the amount of the import tax that Leo paid was $87.50, what was the total value of the item?

Let the value of the item be $x, then 0.07(x-1,000)=87.5 --> x-1,000=1,250 --> x=2,250.

Answer: C.

Else, you could backsolve: If the value of the item is $2,000 the tax is (2,000-1,000)*0.07=70, so the value must be more than $2,000. Eliminate A and B. If the value of the item is $2,400 the tax is (2,400-1,000)*0.07=98, so the value must be less than $2,400. Eliminate D and E.

Only answer choice C is left.

Do you have tips or a guide on how to most efficiently divide with non-integers in the denominator? I have seen two PS questions where they want us to divide some integer value with a non-integer (0.8 and now 0.07), and I do not really know how to properly approach the division.

Since we know Leo pays 7% of the amount that is in excess of $1000 We can assume 'x' to be the excess amount. Then 7 percent of x = 87.50 => x = 1250. Hence total value = 1000 + 1250 = 2250. Hence (C)
