A school has a goal of getting at least 2000 boxtops. They have 872 so far. They have 8 days left to get it. At least how many d
True [87]

Answer:

School needs to collect at least 144 box tops each day to meet their goal.

Step-by-step explanation:

The total requirement of box tops = 2,000

The number of box tops they have already received = 872

So, the box tops left = Total number required- Number of tops received

                                  =2,000 - 872

                                   = 1,128 box tops are left so far.

Number of days left = 8

So, number of minimum tops needed each day = \frac{\textrm{Total tops required}}{\textrm{Number of days left}}

                                                = \frac{1128}{8} = 141

Hence, they need to collect at least 144 box tops each day to meet their goal.
