Question

Tom has read the first 40 pages of a book. He plans to read another 12 pages each day Write an equation that represents the relationship between the total number of pages, p, and the number of days he has been reading , d.

Answer 1

`p=12d+40`

Explanation:

-This is a linear relationship problem modeled as:

`y=mx+c`

where:

• 
  `y` is the quantity at variable x
• 
  `m` is the slope
• 
  `c` is the constant of increment or decrement.
• 
  `x` is the variation variable.

Given the constant 40, and 12 pages per day as the rate of change we substitute our variables in the form of the formula above as:

`p=12d+40`
