Stells [14]

Answer:

The 1st option

Step-by-step explanation:

Because x can be anything that's not imaginary and y has to be below 2 always because of the negative value added before the 3. Also it's impossible to reverse the sign of the negative because negative x would only result in 3 becoming a fraction.

Answer:

The markup rate is 51% on the cost

Step-by-step explanation:

Price of book = 7.99

Cost to the store = 5.29

The markup rate is a term used to figure what percentage is added on to the cost of the item to find its selling price.

If we subtract cost from the price we will know how much is added to actual cost: 7.99 - 5.29 = 2.7

$Markup rate = \frac{added value}{cost}$

$Markup rate = \frac{2.7}{5.29} = 0.51$

Markup rate is 0.51*100 = 51%
