b = 2.35 +0.25x

c = 1.75 +0.40x

In the equations above, b and c represent the price per pound in dollars, of beef and chicken, respectively, x weeks after July 1 during last summer. What was the price per pound of beef when it was equal to the price per pound of chicken?

b=2.35+0.25x

c = 1.75 +0.40x

For equal price per pound of beef and chicken we can write,

2.35 +0.25x = 1.75 +0.40x

⇒ 0.40x-0.25x= 2.35 1.75 ⇒ 0.15x = 0.60 ∴ x= 0.600.15 = 4

x weeks after July 1 during last summer

b=2.35+ (0.25 × 4) = 3.35 ∴ c = 1.75+ (0.40 × 4) = 3.35 answer: 3.35$

A summer camp counselor wants to find a length, x, in feet, across a lake as represented in the sketch above. The lengths represented by AB, EB, BD and CD on the sketch were determined to be 1800 feet, 1400 feet, 700 feet and 800 feet respectively. Segments AC and DE interest at B, and ∠AEB and ∠CDB have the same measure. What is the value of x?
