The volume of blood in a person's body is proportional to body weight. A person who weighs 140 pounds has approximately 4 quarts of blood. Estimate the number of quarts of blood in a person who weighs 190 pounds
To find out the estimated number of quarts of blood in a person who weighs 190 pounds, we can set up a proportion based on the information given:
140 pounds -> 4 quarts
190 pounds -> x quarts
Using the proportion:
(140 pounds) / (4 quarts) = (190 pounds) / x
Cross multiplying:
140x = 760
x = 760 / 140
x ≈ 5.43
Therefore, a person who weighs 190 pounds would have approximately 5.43 quarts of blood.
