Jalen and george earn base salaries plus commission. jalen earns 3200 plus 15% of his sales. george earns 3300 plus 10% of his sales how much do jalen and george have to sell to earn the same amount

$2,000

Step-by-step explanation:

The expression for the amount that Jalen earns is:

$3200 + .15s, where 's' is the amount of sales

The expression for the amount George needs to earn is:

$3300 + .10s, where 's' is the amount of sales

Since you are trying to find how much they have to sell to earn the same amount, you can set the two expression equal to each other:

3200 + .15s = 3300 + .10s

Subtract .10s from both sides:

3200 + .15s - .10s = 3300 + .10s - .10s

3200 + .05s = 3300

Subtract 3200 from both sides:

3200 - 3200 + .05s = 3300 - 3200

0.05s = 100

Divide both sides by 0.05:

0.05s/0.05 = 100/0.05

s = $2,000 in sales
