Answer the following questions. (a) A store is offering a sale of 30% off all items. What is the price of a $24 shirt after
the discount? Round the answer to two decimal places.
(b) A customer paid $16.99 for a shirt that normally sells for $19.99. What percent
discount did the customer receive? Round your answer to the nearest percent.
(c) A customer and a salesperson are arguing about a promotion and a coupon
applied after the promotional discount. The promotion is a 20% discount on all items
in the store. The coupon is an additional 10% off of the order. The customer claims
the 20% discount should be made before the 10% discount. The salesperson claims
it does not matter which order to give the discounts. Who is correct and why? Make
sure you prove your claim and include relevant mathematical calculations - I am a
skeptic and will doubt your answer unless you have enough details to prove your
conclusion.

step-by-step explan mxfcg'k; uafwgzfgjhklhgation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
