Q. Sharon read a

300

-page book. She read at a rate of

15

pages per day in

d

days.

\newline

Write an equation to describe this situation.

Identify Proportional Relationship: Sharon reads at a rate of $15$ pages per day. This means that the number of pages she reads is directly proportional to the number of days she reads. If we let $p$ represent the total number of pages read and $d$ represent the number of days, we can express this proportional relationship with the equation $p = \text{rate} \times d$ . Given that the rate is $15$ pages per day, we can substitute this value into the equation.
Substitute Rate into Equation: Now, we substitute the rate of $15$ pages per day into the equation to get $p = 15 \times d$ . This equation represents the relationship between the number of days Sharon reads, $d$ , and the total number of pages she reads, $p$ .
