Number of votes won by A = p
Number of votes won by B = 35
Number of votes won by B are 125% of the number of votes won by A. So we can write that 35 is 125% of p. In equation form we can translate it as:
35 = 125% of p
35 = 1.25 x p
p = 35/1.25
p = 28
So the number of votes won be A are 28.
Hello! Your answer is B, 10 minutes.
Say the x = minutes taken to do the job. You can set up an equation like this to solve this.
This is representative of the situation. The fractions each represent <u>how much each person does in a minute</u>, and when they're multiplied by x, that's <u>how much of the project they get done</u> based off of the minutes they work together on the job. Add the two together, and you get <u>how much of the project is finished in x amount of time</u>. Set it equal to 1, as you are looking for 100% completion.
Once you have this equation, find a common denominator, add, and solve.
Therefore, it will take them 10 minutes to do the job together.
Hope this helps!
