Answer:
Lauren and Chris will take 40 weeks to run out of their bulk paper towels if they continue using one roll every week and a half.
Step-by-step explanation:
Lauren and Chris use one roll of paper towels every week and a half. Therefore, to calculate how long the 60 rolls will last, we must figure out how many week-and-a-half periods are in the total number of rolls. We do this by dividing the total number of rolls (60) by the rate at which they're used (1 roll per 1.5 weeks).
This calculation is as follows: 60 rolls 1.5 weeks/ roll = 40 weeks. So, it will take Lauren and Chris 40 weeks to use up all of their paper towels if they continue at this usage rate.
