Answer this question:Zilla spent 7% of her monthly earnings on rent, half of it on her other monthly expenses, and put the rest in her savings. If she spent $133 on her rent, how much does she deposit into her savings account in a month?
Since $133 is equal to 7% of her earnings, then 1% is equal to $133 / 7 = $19. The total monthly earning of Zilla is represented by 100%, so $19 x 100 = $1900 is her monthly earnings. So, $1900 / 2 = $950 is spent on her other monthly expenses. The total amount spent on the rent and other monthly expenses is $133 + $950 = $1083. Hence, she saves $1900 - $1083 = $817 per month.
The answer is 817.

Answer this question:A class is completing an art project. Each of the 30 students is assigned to a separate group and will need to take markers from the 22 boxes of markers. The first group has 10 students who will have 2 markers each and the second group has 15 students who will have 4 markers each. The last group takes the remaining markers and divides them equally. If each box of markers contains 5 markers, how many markers does each of the students in the last group receive?
The first group uses a total of 10 students * 2 markers = 20 markers. The second group uses a total of 15 students * 4 markers = 60 markers. This is a total of 20 + 60 = 80 markers. The total number of markers in the boxes is 5 markers * 22 boxes = 110 markers. This leaves 110 – 80 = 30 markers for the last group to split between themselves. The last group is made up of 30 total students – 10 students in the first group – 15 students in the second group = 5 students. Therefore, students in the last group receive 30 markers / 5 students = 6 markers each.
The answer is 6.
