Question 163170: my son is having a problems on a few of his homework. the following one are the ones I have no idea how to figure out, please help me.
1. A local coffee house donaated tweleve pounds of fresh roasted coffee. The students are running a fundraiser at school and decide to sell the coffee in bags. how many bags can be made if each bag contains 3/5 pounds? Explain how to get answer.
2.
The seats in a theater are divded intow two sections. Section A has 15 rows Section B has 13 rows. There are 10 seats in aq row. How many seats are in the theater?
Jamal solved the problem using this method. He multiplied to find the seats in each section, and then added to find the total:
Section A 10 x 15=150
Section B 10x13=130
Total seats (10x15)+(10x13)=150 +130=280
Rosa thinks her method is correct. She added to find the total number of rows and then multiplied by the number of seats per row.
Rows in A and B 15 +13
Total seats 10(15+13)=10x28=280
Who is correct. Explain the answer.
Please explains answers to me so I can explain to him. He in 8th grade. Math is not what I took when I was in 8th grade. Please help a mom who is in need.

Hi, Hope I can help,
.
First problem
.
1. A local coffee house donaated tweleve pounds of fresh roasted coffee. The students are running a fundraiser at school and decide to sell the coffee in bags. how many bags can be made if each bag contains 3/5 pounds? Explain how to get answer.
.
To find the answer, you would take the total number of pounds ( 12 ), and divide the total by how much is in a bag ( ) to get your answer
.
It is saying how many pounds are in 12 pounds. ( pounds is in one bag )
.
Lets do the math
.
= = = = = =
.
They can make bags. ( since there are twenty pounds in 12 pounds, one bag contains pounds )
.
First answer = bags
.
Second question
.
2.
The seats in a theater are divided into two sections. Section A has 15 rows Section B has 13 rows. There are 10 seats in aq row. How many seats are in the theater?
.
This is the way I solve this problem
.
Since each row contains 10 seats, multiply number of seats by number of rows in each section, and that will be how many seats in each Section
.
Section A has 15 rows, = seats
.
Section B has 13 rows, = seats
.
You add the two answers together to get the total number of seats in the theater
.
=
.
Your second answer is seats
.
Here is the way I would put the original equation
.
( Then you solve for "x" from there ), ( This is the same as the way Jamal solved the problem )
.
The other way ( Rosa's way ) is not wrong either
.

.
If we solved
.
= =
.
Lets compare the two ways of solving
.

.
We can use the distributive property to solve this problem as well
.
= = = (This is how Jamal solved)
.
If we multiply the numbers
.
= =
.
As you can see, you can solve this problem, and similar problems in different ways. You can solve math in several different ways sometimes, this is just one of many examples
.
First answer = bags
.
Second answer = seats
.
Hope I helped, Levi
