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
The amount of decrease was 5 -3 = 2 inches,
Percent decrease = 2 /5 = 0.40 x 100 = 40%
P = 21 + 2w
Solve for w
Subtract 21 from both sides.
P - 21 = 2w
Divide both sides by 2.
= w
The first option is correct.
5/10 divide each number by 5, 5 divided by 5 is 1 and 10 divided by 5 is two so it would be 1/2
4/12 divide each number by 4, four divided by 4 is 1, and 12 divided by 4 is 3 so it would be 1/3
3/9 divide each number by 3, 3 divided by 3 is 1, and 9 divided by 3 is 3 or it would also be 1/3
Hope that helped you
24; 240/10 = 24
The answer is 24
