When the price per pound of beef was equal to the price per pound of chicken,
$$b =c$$
The following equation is established
$$2.35+0.25x = 1.75+0.40x$$
$$0.6 = 0.15x$$
$$x = 4$$
which means it took 4 months for the price of beef was equal to the price of chicken after July 1 during last summer.
Plug in x in the first equation
$$b=2.35+0.25	imes x $$
$$=3.35$$
D is correct choice
