Here is a double number line showing that it costs $3 to buy 2 bags of rice:

1. At this rate, how many bags of rice can you buy with $12? ___________

2. Find the cost per bag. _____________

3. How much do 20 bags of rice cost? _____________

Answers

Answer:

1. 8 bags of rice

2. $1.50 per bag

3. $30

Step-by-step explanation:

For #1, you set up the proportion 3 over 2 is equal to 12 over x and solve by cross multiplication. Then, you should get the answer of 8 bags. For #2, you do $3 divided by 2 to get the answer of $1.50. For #3, you use your answer from #2 and do 1.5 times 20 to get $30.

1. The cost of 12 bags of rice is 18 dollars.

2. Per bag of rice cots 1.5 dollars.

3. The cost of 20 bags of rice is 30 dollars.

What is a unitary method?

A unitary method is a mathematical technique for determining the value of a single unit then we can derive any no. of units by multiplying it by the single unit.

Given it costs 3 dollars for 2 bags of rice.

We know if we determine the cost of one bag of rice we can find out the cost of any no. bags of rice.

∴ 2 bags of rice cost 3 dollars,

So, 1 bag of rice cots (3/2) dollars = 1.5 dollars.

1. At the rate of 1.5 dollars per bag of rice 12 bags of rice will cost (1.5×12) dollars = 18 dollars.

2. The cost per bag of rice is 1.5 dollars.

3. The cost of 20 bags of rice is (1.5×20) dollars = 30 dollars.

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 5 rows of the same length, he has 3 chairs left over. If he arranges the chairs in 3 rows of that same length, he has 15 left over. How many chairs does Liam have?

Answers

Answer:

33 chairs

Step-by-step explanation:

c= chairs per row

5 rows of (c) chairs  plus 3 chairs   is equal to 3 rows of (c)chairs plus 15 chairs)

5c +3 = 3c +15

 2c=12

c= 6           ( 6 chairs per row)

 5x6 = 30

   30+3 = 33

                        3x6=18

                         18+15 = 33
