Asalesperson set a goal to earn $3,000 in july. he receives a base salary of $1,200 per month as well as a 10% commission for all sales in that month. how many dollars of merchandise will he have to sell to meet his goal?

$18,000

Step-by-step explanation:

Target is 3000, out of which 1200 will already be earned from salary. So he needs 3000 - 1200 = 1800 from commissions.

As we know, 10% is the commission rate, we need to know "Which numbers' 10% will give us 1800??"

Thus let total sales be x, so we can write 0.1x=18,000

Solving gives us:

He needs to sell $18,000 worth of merchandise to meet his income target for July.
