Mark works at a shoe store for 30 hours a week and earns $8.75. during one week mark sold $480 in shoes. if he receives a 5% commission on his sales of the shoes, what is his total salary for the week?

I'm assuming you mean he earns $8.75 an hour.

So first we have to find out how much money Mark gets without any commission. We do this by multiplying 30 and 8.75 and getting $262.50 .

Then, we have to find the commission. 5% as a decimal is .05, and in order to get 5% of a number, we multiply the 5% and the number together. In other words, we now have to multiply .05 and 480 together, which results in 24.

In conclusion, as a total salary, Mark earns $262.50 + $24, or $286.50
