At a school supply store, binders cost $5 and pencil pouches cost $2. In one day, 42 of these items are sold for total sales of $144. Which system represents this (b represents binders and p represents pencil pouches), and how many binders were sold?

Answers

Answer:

Part 1) The system of equations that represent this situation is equal to

b+p=42  and 5b+2p=144

Part 2) 20 binders were sold

Step-by-step explanation:

Let

b -----> the number of binders sold

p -----> the number of pencil pouches sold

Part 1)

we know that

The system of equations that represent this situation is equal to

b+p=42

5b+2p=144

Part 2) How many binders were sold?

we have

b+p=42

p=42-b ------> equation A

5b+2p=144 -----> equation B

substitute equation A in equation B

5b+2(42-b)=144

5b+84-2b=144

3b=144-84

3b=60

b=20 binders

There are 18 questions on the test. Each question is worth either four or five points. The total is 80 points. How many questions of each type are on the test?

Answers

Answer: the number of four point questions in the test is 10.

the number of five point questions in the test 8

Step-by-step explanation:

Let x represent the number of four point questions in the test.

Let y represent the number of five point questions in the test.

There are 18 questions on the test. It means that

x + y = 18

Each question is worth either four or five points. The total is 80 points. This means that

4x + 5y = 80 - - - - - - - - - - - - - -1

Substituting x = 18 - y into equation 1, it becomes

4(18 - y) + 5y = 80

72 - 4y + 5y = 80

- 4y + 5y = 80 - 72

y = 8

x = 18 - y = 18 - 8

x = 10
