Q. Sharon read a 300-page book. She read at a rate of 15 pages per day in d days.Write an equation to describe this situation.
Identify variables and constants: Identify the variables and constants in the situation.Sharon reads a 300-page book, so the total number of pages is a constant, 300 pages.She reads at a rate of 15 pages per day, so the rate is another constant, 15 pages/day.The number of days she reads is the variable we are looking for, represented by d.
Set up equation: Set up the equation based on the given information.We know that the total number of pages read is equal to the rate of reading per day multiplied by the number of days.So, the equation is: Total Pages = Rate × DaysIn this case, it translates to: 300=15×d
Check for errors: Check the equation for any mathematical errors.The equation 300=15×d correctly represents the situation where the total number of pages read (300) is the product of the rate of reading (15 pages/day) and the number of days (d).
