expeople1 [14]
After x weeks:
Jules will have: 1,200 + 40 x.
Kelsey will have: 400 + 50 x.
If we want to know in how many weeks will they have the same amount of money, we will make an equation:
400 + 50 x = 1,200 + 40 x
50 x - 40 x = 1,200 - 400
10 x = 800
x = 800 : 10
x = 80
Answer: In 80 weeks they will have the same amount of money.

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.
