Lizzy: Tree Elementary School is raising money for a new playground. Mrs. Johnson’s class raised $2300, which is twice the amount that Mrs. Sutton’s class raised. Mrs. Sutton’s class raised 8 times less than Miss Rollin’s class. Miss Rollin’s class raised a third of the total amount raised by the school. How much money did the school raise for the playground if 2% will be deducted for administration fees?.
Me: Hmmm, let me think. I think this is the detailed solution:
Find the amount Mrs. Sutton’s class raised by dividing $2300 by 2. $2300 / 2 = $1150. Find the amount Miss Rollin’s class raised by multiplying $1150 by 8. $1150 x 8 = $9200. Multiply $9200 by 3 to find the total amount raised. $9200 x 3 = $27600. Convert 2% to decimal. 2 / 100 = 0.02. Multiply $27600 by 0.02 to find the administration fees. $27600 x 0.02 = $552. Subtract the administration fee from the total amount raised. $27600 - $552 = $27048. Final answer: 27048.
