Set up the following word problem as a proportion and solve. then write your answer as a complete sentence.
a health department estimates that 8 vials of malaria serum will treat 100 people. at this rate, how many vials are required to treat 175 people?

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
