The owner of a health food store is developing a new product that consists of peanuts and raisins. Raisins cost

\$2.50

per pound and peanuts cost

\$3.50

per pound. The owner wants to create

20

pounds of the product that cost

\$3.03

per pound. Which of the following systems of equations can be used to determine the number of pounds of peanuts,

p

, and the number of pounds of raisins,

r

, that should be combined?

Choose 1 answer:

A
$\begin{aligned}\\ p - r &= 20\\ \\ \qquad\dfrac{3.50p+2.50r}{20} &= 3.03\\ \\ \end{aligned}$
B
$\begin{aligned}\\ p + r &= 20\\ \\ \qquad\dfrac{3.50p+2.50r}{20} &= 3.03\\ \\ \end{aligned}$
C
$\begin{aligned}\\ p - r &= 20\\ \\ \qquad3.50p+2.50r &= 3.03\\ \\ \end{aligned}$
D
$\begin{aligned}\\ p + r &= 20\\ \\ \qquad3.50p+2.50r &= 3.03\\ \end{aligned}$
