2. On a school picnic, a group of girls agree to pay equally for the use of a boat and each pays * 25. If there had been 3 more girls in the
group, each would have paid 5 less. How many girls were there
in the group?

There were 12 girls in the group

Step-by-step explanation:

Assume that the number of girls at first is x

∵ There were x girls in a group

∵ Each girl pays 25 to use a boat

∴ The amount paid = 25 × x

∴ The amount paid = 25x

∵ If there had been 3 more girls in the group

→ That means add x by 3

∴ The number of girls in the group = x + 3

∵ Each would have paid 5 less

∴ Each girl would have paid 25 - 5 = 20

∴ Each girl would have paid 20

∴ The amount paid = 20 × (x + 3)

∴ The amount paid = 20(x) + 20(3)

∴ The amount paid = 20x + 60

→ Equate the right sides of the amount paid

∵ 25x = 20x + 60

→ Subtract 20x from both sides

∴ 25x - 20x = 20x - 20x + 60

∴ 5x = 60

→ Divide both sides by 5 to find x

∴ x = 12

∵ x represents the number of the girls in the group

∴ There were 12 girls in the group
