Isabel bought a new jacket for $48 before tax. she paid 6.5% in sales tax. how much was the sales tax?
a)$2.68
b)$2.92
c)$3.12
d)$3.08

Basing on the data provide above, if Isabel bought the jacket for $48.00 and sales tax is equal to 6.5% which is basically 0.065, we can multiply 0.065 * 48.00 which will be equal to $3.12. So going back to the options the answer is C. which is $3.12.
