Answer:

If an inequality constraint holds as a strict inequality at the optimal point (that is, does not hold with equality), the constraint is said to be non-binding, as the point could be varied in the direction of the constraint, although it would not be optimal .There are two types of inequality constraints: limits on variables, often called explicit constraints such as Equation.The following table will make you even clear!

1. Marcus bought a $40.00 tennis racket. He has a coupon for 20% off. The Sales tax where he bought the tennis racket is 6%. a.

jeka94

Answer:

$33.92

Step-by-step explanation:

First, we have to find how much the sale price for the tennis racket is before tax.

100% - 20% = 80% Marcus has to pay 80% of the original price.

80% * 40 = .8 * 40 = 32

Marcus has to pay $32 for the tennis racket before tax.

6% = .06 (tax percentage)

.06 * 32 = 1.92 ————> tax

Add the tax with the sale price.

32 + 1.92 = 33.92

Marcus has to pay $33.92 for the tennis racket.

2x²*x=2x³
2x²*3=6x²
6x*x=6x²
6x*3=18x
-8*x=-8x
-8*3=-24
