The red cross is holding blood drives in two locations. in one day, center 1 collected 715 pints and center 2 collected 1035 pints. write and evaluate an expression to estimate the total number of pints of blood donated over a 3-day period.

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.

the circle one

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
