Step-by-step explanation:

Inequalities of the form | x | < a , always have solutions of the form

- a < x < a

Given | x - 12 | < 3, then

- 3 < x - 12 < 3 ( add 12 to all 3 intervals )

Casey buys a bracket for. She pays for the bracelet and pays $0.72 in sales tax. The sales tax is 6%. What is the Original price

iren2701 [21]

Answer:

$12

Step-by-step explanation:

amount of tax = $0.72

percent of tax= 6%

Let the original cost be x

so that

6% of x= 0.72

solve for x

6/100*x= 0.72

0.06x= 0.72

divide both sides by 0.06

x= 0.72/0.06

x=$12

Hence the cost is $12
