The amount of blood in a person's body varies directly with body weight. a person who weighs 160 lb has about 4.6 qt of blood. about how many quarts of blood are in the body of a 175-lb person?
-how can you find the constant of variation?
-can you write an equation that relates quarts of blood to weight?
-how can you use the equation to determine solution?

Step-by-step explanation:

Given that amount of blood is directly linked to body weight of the person.

b = Amount of blood

W = weight of the person

k = proportionality constant or constant of variation

1) Given that, person who weighs 160 lb has about 4.6 quart of blood.

b = 4.6 quart, W = 160 lb

The constant of variation is of value 0.02875 quart/lb.

2) An equation that relates quarts of blood to weight:

3) If, b = ?,W = 175 lb

5.03125 quarts of blood are in the body of a 175-lb person.
