Question

A discount book store sells hardcover books for $8 each and paperbacks for $4 each. The number of hardcover books, h, sold one day was 2 more than four times the number of paperback books, p, sold that same day. The total amount of sales for that day was $160. Jean-Paul wrote the following system of linear equations to find the number of each type of book sold. 8 h 4 p = 160. P = 4 h 2. What is Jean-Paul’s error? Jean-Paul should have written the first equation as h p = 160. Jean-Paul should have written the first equation as 4 h 8 p = 160. Jean-Paul should have written the second equation as h = 4 p 2. Jean-Paul should have written the second equation as p 2 = 4 h.

Answer 1

The equations are h + 2 = 4p and h + p = 160.

Linear system

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

A discount book store sells hardcover books for $8 each and paperbacks for $4 each.

The number of hardcover books, h, sold one day was 2 more than four times the number of paperback books, p, sold that same day.

The total amount of sales for that day was $160.

To find

The equations.

How do find the equations?

According to the condition,

The number of hardcover books, h, sold one day was 2 more than four times the number of paperback books, p, sold that same day.

h + 2 = 4p.....1

The total amount of sales for that day was $160.

h + p = 160.....2

The equations are h + 2 = 4p and h + p = 160.
