Answer:
75 students
Step-by-step explanation:
So firstly lets make convert these words to alegbra :
30 people are 40%of the total students at the event meaning that the following equation can be made :
30 = 40% of x (x is the unknown amount of students there)
30 = 40% * x
30 = 0.4x (we can convert the precentage into a decimal by dividing by 100)
Now that we have the equation that 30 = 0.4x we can evalute it and find x :
30=0.4x
30/0.4=0.4x/0.4 (divide by 0.4 on both sides)
75=x
So thats how we get that 75 students were in the event in total.
