To calculate the total number of pints of blood donated over a 3-day period, we make an expression as follows:

Total = 715X + 1035X

where X is the number of days.

Therefore, the total number of pints is equal to 5250 pints of blood.

Answer:

5,250 pints of blood

Step-by-step explanation:

The Red Cross is holding blood drives in two locations.

In one day, Center 1 collected blood = 715 pints

and Center 2 collected blood = 1035 pints

Let the number of pints donated over a 3-day period be x.

so the expression will be

x/3 = 715+1035 (since the number of pints of blood donated in one day is the sum of pints collected in both the centers in one day )

x = 3( 715 + 1035 )

= 3 × 1,750

= 5,250 pints of blood

Total 5,250 pints of blood donated over a 3 days period.
