Question

Explanation Please???

Answer 1

We know that Center 1 collects 715 pints per day and Center 2 collects 1035 pints per day.

They are asking for the estimated combined amount of blood from both centers in 3 days.

Estimate 715 as 700, and 1035 as 1000

This is written as

3(700+1000)= estimated total amount

To evaluate, simplify.

3(1700)= 5100 pints in 3 days from both centers
