Let’s check out your problem:

P=(19)/(2)+(4)/(25)d
The amount of paint, P, in pints, that an art sthtio can buy with d dollars is given by the equation. What is the best interpretation of (4)/(25) as shown in the equation?
Choose 1 answer:
(A) The paint costs 4/25 of a dollar per pint
(B) One dollar can buy 4/25 of a pint of paint.
(C) The art studio started with 4/25 of a pint of paint.
(D) The art studio can purchase at most 4/25 of a pint of paint.

Q. P=192+425dP=\frac{19}{2}+\frac{4}{25}d\newlineThe amount of paint, PP, in pints, that an art studio can buy with dd dollars is given by the equation. What is the best interpretation of 425\frac{4}{25} as shown in the equation?\newlineChoose 11 answer:\newline(A) The paint costs 425\frac{4}{25} of a dollar per pint \newline(B) One dollar can buy 425\frac{4}{25} of a pint of paint. \newline(C) The art studio started with 425\frac{4}{25} of a pint of paint. \newline(D) The art studio can purchase at most 425\frac{4}{25} of a pint of paint.
  1. Interpreting the Fraction: We are given the equation P=192+425dP = \frac{19}{2} + \frac{4}{25}d, where PP represents the amount of paint in pints that an art studio can buy with dd dollars. To interpret the fraction 425\frac{4}{25}, we need to understand its role in the equation.
  2. Role of Fraction in Equation: The fraction (425)(\frac{4}{25}) is multiplied by the variable dd, which represents the number of dollars. This suggests that (425)(\frac{4}{25}) is the rate at which the studio can buy paint per dollar.
  3. Confirmation with d=1d=1: To confirm this interpretation, we can think of dd as 11 dollar. If d=1d = 1, then the studio can buy 425\frac{4}{25} pints of paint for 11 dollar, according to the equation P=192+425dP = \frac{19}{2} + \frac{4}{25}d.
  4. Rate of Paint per Dollar: Therefore, the fraction (425)(\frac{4}{25}) represents the amount of paint in pints that the studio can buy with 11 dollar. This is the rate of paint per dollar.
