32 people volunteers to donate blood. n dident have he health requirment so they couldent donate the rest of the volunteers dona
Vesna [10]

Answer:

the equation representing total amount of blood donated is 470(32-n)=15040-470n \ ml.

Step-by-step explanation:

Total number of volunteers = 32

number of volunteers couldn't donate blood = n.

So Number of volunteers who donated blood can be calculated by subtracting number of volunteers couldn't donate blood from Total number of volunteers.

Framing in equation form we get;

So, the number of remaining volunteers who donated blood = 32-n.

Each of these volunteers donated blood = 470 ml

Now Total Amount of Blood donated is equal to Amount each of these volunteers donated blood times the number of volunteers who donated blood.

Framing in the equation form we get;

total amount of blood donated  milliliters = 470(32-n)=15040-470n \ ml

Hence the equation representing total amount of blood donated is 470(32-n)=15040-470n \ ml.

One number is 9 more than twice another. Their difference is 22. What is the larger number? 13 31 35
aleksandr82 [10.1K]

x and y

x=2y+9

x-y=22

*x is the larger number*

plug in x to solve for y

2y+9-y=22

y+9=22

-9 both sides

y=13

plug in y and solve for X

x=2 (13)+9

x=26+9

x=35

A merchant buys a television for $125 and sells it for $75 more.What is the percent of markup?
cestrela7 [59]
Since he sold it for $75 more,

% Mark Up = Mark Up/ Cost Price  x 100%

% Mark Up =   75 / 125 x 100%      =   0.6  x 100% = 60%

Percent Mark Up = 60%
Hope this helps :)
