Question

Liz wanted to buy a new book. When she checked the price last week, it was $19. This week, the same book was listed for $22. Write and solve an equation to show how much the book increased in price.

22 = p + 19; p = $3
22 = p − 19; p = $41
19 + p = 41; p = $22
2p = 22; p = $11

Answer 1

The price of the book increased by $3, calculated by subtracting the original price of $19 from the new price of $22.

Step-by-step explanation:

The question involves solving a simple linear equation to determine the change in the price of a book. Liz observed that the price of a book increased from $19 last week to $22 this week.

To find the increase in price, represented by p, we can set up the following equation: 19 + p = 22.

Solving for p, we subtract 19 from both sides of the equation, which gives us p = 22 - 19, which simplifies to p = $3.

Answer 2

Answer:22=p+19;p=$3
