Mathematics: Before a renovation, a movie theater had 135 seats. after the renovation, the theater has 166 seats. what is the approximate percentage increase of the number of seats in the theater? if necessary, round to the nearest tenth of a percent. a. 18.7% b. 21.3% c. 37.5% d. 23%

x=6,y=3Step-by-step explanation:x−2y=0⇒x=2ySubstitute x=2y into 4x-3y=15, we get :4(2y)−3y=158y−3y=155y=15⇒y=3x=2y=2×3=6...

Step-by-step explanation:

the percentage increase is found using

percent increase = $\frac{increase}{original}$ × 100%

increase = 166 - 135 = 31, hence

percent increase = $\frac{31}{135}$ × 100% = 22.96 ≈ 23% → D

⇒

Substitute x=2y into 4x-3y=15, we get :4(2y)−3y=158y−3y=155y=15⇒y=3x=2y=2×3=6
