Answer:
$4871.25
Step-by-step explanation:
You know that the dirt bike has been "marked down," so to find the percentage of the original cost, subtract 0.12 from 1 to get 0.88. Then, define x as the original cost, and set up an equation:
0.88x = 4286.70
You know that 4286.70 is 88% of the original cost, so 0.88 times the original cost will equal the marked down cost. Now, divide both sides by 0.88 to get the answer:
x = 4871.25
Step-by-step explanation:
W × ( 3 / 7 ) = 24 ;
