Isaiah is trying to buy dry-erase markers for his teachers during teacher appreciation week. He is able to collect 12 markers a day and started off with 15. How many days will it take him to reach 135 markers?

Create an equation to solve the problem using \( m \) for markers and \( d \) for days.

Answer :

Isaiah can collect 135 dry-erase markers in 10 days by collecting 12 markers a day, starting with an initial count of 15 markers

The student's question involves setting up and solving an equation to determine the number of days Isaiah needs to collect a sufficient number of dry-erase markers.

We can represent the total number of markers collected (m) as a function of the number of days (d) he collects them. Isaiah starts with 15 markers and collects 12 each day. So the equation will be:

m = 12d + 15

To find out how many days it will take for Isaiah to reach 135 markers, we substitute 135 for m in the equation and solve for d:

135 = 12d + 15

Subtracting 15 from both sides, we get:

120 = 12d

Dividing both sides by 12, we find:

d = 10

Therefore, it will take Isaiah 10 days to collect 135 dry-erase markers.

Answer:

It will take him 10 days to get to 135 markers.
