Question

You make both rocking chairs and bar stools. You charge $100 for every rocking chair and $40 for every bar stool. Which expression represents your income if you sell r rocking chairs and b bar stools?

Answer 1

100r+40b=income
You have to multiply $100 per rocking chair and add it to $40 per bar stool to get our income.

Answer 2

The answer is
`Income=100*r+40*b`

Explanation:

In this case we have to construct an expression that describe the income of selling the rocking chairs ($100 each - r) and the bar stool ($40 each - b), so the total income will depend on the addition of this two variables multiplied by its individual price, this is:

`Income=100*r+40*b`

The answer is
`Income=100*r+40*b`
