How much would Connor make in a week in which he made $2175 in sales? How much would Connor make in a week if he made xx dollars in sales?

Earnings when selling $2175:??

Earnings when selling $x: ??

Answer 1

`Earnings = 308.75` ---- (a)

`Earnings = 300 + 0.05x` -- (b)

Explanation:

Given

`Base\ Salary = 300`

`Commission = 5\%`

Solving (a): Sales of $2175 in a week.

His total earnings is calculated as thus:

`Earnings = Base\ Salary + Commission * Sales`

`Earnings = 300 + 5\% * 2175`

`Earnings = 300 + 108.75`

`Earnings = 308.75`

Solving (b): Sales of $x in a week.

His total earnings is calculated as thus:

`Earnings = Base\ Salary + Commission * Sales`

`Earnings = 300 + 5\% * x`

Convert percent to decimal

`Earnings = 300 + 0.05 * x`

`Earnings = 300 + 0.05x`
