Answer:
40 people voted in total.
Step-by-step explanation:
All right, this looks fun.
So, we know 36 students are 90% of the people that voted, and we want to find the total amount of people that voted.
The question we are really asking is "36 is 90% of what?"
To solve this, we set up an equation and solve for x.
36 = 0.90 * x
To get x alone divide by 0.90 on both sides.
36 divided by 0.90 = 40
Therefore 40 people voted in total.
