Kenya Kon sells dishwashers. He earns an 8% commission on sales. How much must be sell in order to earn $3000?

Karolina [17]

Use a variable to solve for this.

x * .08 = 3000

Divide by .08 on both sides.
x = 37500

We can check this by inputting 37500 for x.

37500 * .08 = 3000
3000 = 3000

Kenya Kon must earn $37500 to earn $3000.
