The first step to solving this problem is to find out how much money Sandra received for her birthday. We can find this out by multiplying 15 by 20,, which will look like the following:
15 x 20 = 300
Now that we know that Sandra received a total of $300 for her birthday,, we need to multiply the 300 by
to see how much she spent.
300 x
First we need to reduce the numbers with 5
60 x 3
Then multiply the numbers together to find out how much money Sandra spent
180
Now,, we need to multiply 300 by
to see how much of her money she saved
300 x
Reduce the numbers with 5
60 x 2
Then multiply the numbers together to see how much money Sandra saved.
120.
This means that Sandra spent $180 and saved $120.
