One health club charges a $40 membership fee and $40 per month. Another club charges a $100 membership fee and $25 per month. Write and solve an equation to find the number of months that it will take for the two health clubs to be equal

After 4 months, the charges will be same.

Step-by-step explanation:

Membership charges of club one = $40

Per month charges = $40

Let,

x be the number of months

y be the total amount

y = 40x + 40

Membership charges of club two = $100

Per month charges = $25

y = 25x + 100

For equal charges, both equations will be same

40x + 40 = 25x + 100

40x - 25x = 100 - 40

15x = 60

Therefore,

After 4 months, the charges will be same.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
