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
To get percent error you take actual-predicted and divide by the actual then multiply by 100 to get the percent.
65-50=15
15/60=0.25
0.25 times 100 =25%
