A pair of shoes cost $45. The shoes are on sale for 60% off. What is the discount amount?

$27.00

Step-by-step explanation:

To find the discount amount, multiply the discount rate by the cost of the shoes

discount rate * price of shoes

The discount rate is 60% off, and the shoes cost $45

60%*45

Convert 60% to a decimal by dividing by 100, or moving the decimal place over 2 spots

60/100=0.60

60.—>6.0–>0.60

0.60*45=27

The discount amount is $27.00

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
