∠A and \angle B∠B are supplementary angles. If m\angle A=(7x+3)^{\circ}∠A=(7x+3) ∘ and m\angle B=(7x+23)^{\circ}∠B=(7x+23) ∘ , then find the measure of \angle A∠A.

Step-by-step explanation:

That must suck having to do that math

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
