Required

The percentage increase

Step two:

Percentage increase= change in price/ old price *100

Percentage increase=1.14/0.25 *100

Percentage increase=4.56*100

Percentage increase=456%

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
