PLEASE HELP!! REALLY STUCK!

Answer 1

200x15%=30$ of commission
80+30=110$ in total for the week

Answer 2

An easy way to do this specific problem is to divide 200 by 2, since it's just two 100s. Now that you have two 100s, it's easy to see that 15% of 100 is 15. Since you have two 100s, multiply 15 by two. In the future, to calculate percentages, use this formula:

is/of = percent/100

is/200 = 15/100
200 * 15 = 3,000
3,000 / 100 = 30

Just add the commission to the amount she earns each week to her total income for this week.

30 + 80 = 110

Renee earned a total of $110 (B) and earned $30 (C) from commission.
