If a salesman has a base salary of $2,000 per month and makes an additional 4% on every sale, how much merchandise must he sell in a year to make $60,000?

$900,000 merchandise.

Step-by-step explanation:

Salesman has a base salary of $2000 per month.

He makes additional 4% on every sale.

So expression for his earning will be

Earnings = 12(2000) + 4% of x

              = Where x is the additional on every sale

Earnings = 12(2000) + 0.04x

If earnings are $6,000 then

6,000 = 24000 + 0.04x

0.04x = 60,000 - 24,000

0.04x = 36,000

x = = $900,000 merchandise.

its the fourth option
