A clothing store is having a 45% off sale. If you saved $15 on a pair of jeans, how much did they cost normally?

$21.75

Step-by-step explanation:

15 * 0.45 = 6.75

15 + 6.75 = $21.75

2

step-by-step explanation:

1+1=2

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
