Question

Cam bought some used books for $4.95. He paid $0.50 each for some books and $0.35 each for the others. He bought fewer than 8 books at each price. How many books did Cam buy? SHOW/TYPE WORK

Answer 1

4.95 is how much he paid so you cannot go past that number
he bought 7 books at .35 cents, he spent 2.45 on that [ 7 x 0.35 ]
he bought 5 books at .50 cents , he spent 2.50 on that [ 5 x .50 ] 
2.45 plus 2.50 = 4.95 
7 plus 5 = 12
He bought 12 total books

Answer 2

Cam bought 12 books if Cam bought some used books for $4.95. He paid $0.50 each for some books and $0.35 each for the others.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Cam bought some used books for $4.95.

He paid $0.50 each for some books and $0.35 each for the others.

He bought fewer than 8 books at each price.

He bought 7 books at $0.35,

He spent = 7x0.35

                = $2.45

He bought 5 books at $0.50,

he spent = 5x0.50

               = 2.50

= 2.45 + 2.50

= $4.95

Number of books = 7 + 5

Number of books  = 12

Thus, Cam bought 12 books if Cam bought some used books for $4.95. He paid $0.50 each for some books and $0.35 each for the others.
