1. 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\times x

=3.35

D is correct choice
