Question

Fun Land theme park has a total of 110 males and females who are employed at the park. If the number of males is 20 more than twice the number of females, how many males are employed at the park?

A. 80

B. 70

C. 30

D. 20

Answer 1

let x = number of males
y = number of females

it says the total is 110 so

x + y = 110

the number of men is 20 more than twice the number of females

so x is 20 more than twice the number of y

x = 20 + 2y

now substitute this "x" into that other x

x + y = 110
20 + 2y + y = 110
20 + 3y = 110
3y = 110 - 20
3y = 90

can you continue now?

Answer 2

note: this is just y

Answer 3

you're looking for x

Answer 4

y=30

Answer 5

correct

Answer 6

so to find x

x + 30 = 110

Answer 7

solve for x now

Answer 8

110-30=x
80=x
