Finger [1]

The goal amount of the student groups are given in percentages, which are fractions based on one hundred.

  • <u>The flutist raised more money than the trumpeters</u>
  • <u>The difference in the amounts the student raised is $256.5</u>

Reasons:

The amount the school band is raising for the trip = $9,500

Goal of the flutist = To raise 18% of the total amount

Goal of the trumpeters = 85% of the flutist's goal

Required:

The group that raise more money, given that their goals are met

Solution:

Given that the goal of the trumpeters trumpeters is 85% of the goal of the flutist, <u>the flutist raised more money</u>.

Required:

The difference in the amount raised by the students

Solution:

The amount raised by the flutist = 18% of $9,500 = 0.18 × $9,500 = $1,710

Amount the trumpeters raised = 85% of $1,710 = 0.85 × $1,710 = $1,453.5

The difference in the amount raised = $1,710 - $1,453.5 = <u>$256.5</u>
