Money Word Problem

Let us analyze the given problem.

What is asked?

The greatest donation that Anthony and Jennifer can make.

What are the given?

Anthony's money - 30 dollars

Jennifer's money - 36 dollars

Finding the greatest donation that they can make, means finding their greatest common factor. Then, find out how many of their common factor they can get from their money.

How to find the greatest common factor?

There are three steps to find the GCF of two numbers:

1. Find all the factors of each number.

2. Find the common factors.

3. Choose the greatest factor or number.

Solution:

30 = 1, 3, 5, 6, 10, 30

36 = 1, 2, 3, 4, 6, 9, 12, 36

The greatest common factor is 6.

Now we need to know how many sixes we can get from their money.

30 = 6+6+6+6+6

36 = 6+6+6+6+6+6

Therefore, we can get 5 sixes from their money.

5 × 6 = 30

Final

The greatest donation that they can make is 30 dollars.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
