The classrooms are trying to raise $1,200.00 for charity.Mrs. LeBlanc's class has raised 50%.
Mr. Patel's class has raised $235.14
Ms. Warner's class has raised 1/3 as much as Mrs. LeBlanc's class.
How much more money is needed to reach the goal of $1,200.00?

Answers

Answer:

The classes need to raise $164.86 more to reach their goal of $1200.

Step-by-step explanation:

$1,200 total

Mrs. LeBlanc's class has raised 50% of the total, so they've raised $600.

1200/2 = 600

Mr. Patel's class has raised $235.14.

235.14 + 600 = 835.14

Ms. Warner's class has raised 1/3 of the total of Mrs. LeBlanc's class ($600), so they've raised $200.

600/3 = 200

835.14 + 200 = 1035.14

The three classes have raised a combined total of $1035.14.

1200 - 1035.14 = 164.86

The classes need to raise $164.86 more to reach their goal of $1200.

Answer: $164.86
