Step-by-step explanation:
Too lazy to explain 6 factorings on mobile. Trust me if it pleases you.
You will take 140 times 5 since that is the amount she made so you times it buy the price she earns then after you do that subtract it buy 650 since that is what you have to pay
140 x 5 = 700
700 - 650 = 50
so she made a profit of 50
A. 45/100 reduced = 9/20
(divided 45 and 100 by 5 to get 9 and 20)
B. she has finished 27 problems, which is 45% of her homework. In other words
45% of the total problems = 27
if we use X to represent the total amount of problems, then:
45% X = 27
we solved in part A for 45%, which is 9/20, so then:
9/20 x = 27
now all that's left is to solve for x
first multiply both sides by 20
9x = 540
now divide both sides by 9
x = 60
the total amount of problems, or the number of problems she was assigned is 60 problems.
C. If the total amount of problems she had to do was 60, and she has already done 27, then
60 - 27 = the amount of problems she has left
33 = the amount of problems she has left
she has 33 problems left to do.
