Shirts are on sale for 30% off. the original price of one shirt is $15. what is the total cost, in dollars, of 2 of these shirts at the sale price, including a 7% sales tax? enter your answer in the space provided.

 =22.47

Step-by-step explanation:

We are buying 2 shirts

Before discount  2*15 = 30

We get 30% off.  That means we pay 70 percent of the price

$30 * 70% =

30 *.7

21

The cost of the shirts before tax is 21 dollars

Tax is the cost of the shirts after discount  times the tax rate

tax = 21 * 7%

tax = 21 *.07

tax =1.47

We add the tax to the cost of the shirts

Final cost = discount price + tax

                =21+1.47

                =22.47

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
