If a mixture of ground meat consists of 2 pounds of veal that costs x dollars per pound, and 5 pounds of beef that costs y dollars per pound, what is the cost, in dollars, per pound of the mixture?
$$A.\ 2x\ +\ 5y$$
$$B.\ \frac{2x+5y}{xy}$$
$$C.\ 5\left(2x+5y\right)$$
$$D.\ x+y$$
$$E.\ \frac{2x+5y}{7}$$
The OA is E.
I'm really confused by this PS question. Experts, any suggestion about how can I solve it? Thanks in advance.
