Answer:
$2,000
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
