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.
