3,000 / 60 is the better estimate. By rounding down the number of bottles and rounding up the amount needed by department, they won't have a shortage.

True or False: It is useless to find the exact answer to a division problem and then round the quotient.
True! Estimating is supposed to provide a quick way to find a close answer. If you do the long division and then round the answer, that defeats the purpose!!!

Shana wants to buy a PS5 Digital Edition. It costs $399.99. She will save money for 13 weeks. Which is a better way for her to estimate how much she will need to save each week: 360 / 12 = 30 or 480 / 12 = 40? Explain.
480 / 12 = 40. If she rounds the price down, then she will not have enough money saved at the end of 13 weeks.
