Question

a salesperson has averaged $120 in commissions for each of the past ten days. For how many days must her commissions average $160 in order to bring her overall average to %150?

Answer 1

OKOK

A salesperson averaged $120 per 10 days sooo 120/10 is 12 so about 12 per day

So,
You guess the amount that could make up a number around 150or 160

So 12 x3 = 36 + 120=156 hallelujah!

So, 3 more days until she can average $160 in order to bring her overall average to 150%.....

Hope this helps. :::)))))
