Eduardo earns a base salary of $30,000 per year and earns $1,875 per car he sells. Which equation can be used to find the number of cars, c, that Eduardo sold in a year he made 46,875 ?

The equation is, A =30,000 + 1875n.

He sold 9 cars the year he made that amount of money.

Step-by-step explanation:

Before calculating, let's assign letters to certain variables:-

✓ let "A" be used to represent the total amount earned after adding his base salary to the amount he earned as commission per car he sells.

✓ "P" will be used to represent his base salary (a constant = 30,000)

✓ "n" will represent the number of cars sold within a given year.

✓ "B" will be used to represent his commission per car he sells.

Fixing them into a formula, we have:

A = P + n(B)

Since "P" and "B" are constants of 30000 and 1875 respectively, we substitute the letters for their actual amount in the formula:-

A = 30,000 + n(1875)

A = 30,000 + 1875n +This is now the equation that can be used to calculate the number of cars he sold in the year he earned 46,875).

So, since "A" is now $46,875, we substitute accordingly to find the number of cars he sold in the year he earned such amount.

46,875 = 30,000 + 1875b

1875n = 46,875 - 30,000

1875n = 16875

n = 16875/1875

n = 9 cars

Therefore the equation to be used to determine how many cars he sold when he earned $46,875 is:

A = 30,000 + 1875n

He sold 9 cars the year he earned $46,875.
