There are 60 minutes in an hour and percent means per one hundred so:
p/100=18/60
p=1800/60
p=30%
X= sales tax %
Step 1:
$240 * sales tax %= $12
240 * x= 12
240x=12
Divide both sides by 240
x= 0.05 (decimal of the %)
Convert to %:
Multiply decimal by 100 (or move decimal to the right two decimal places
=0.05 x 100
=5 %
The sales tax is 5%.
Hope this helps! :)
