Problema Solution
A shirt which regularly sells for $40 is on sale at a 15% discount. Find the total cost of the jacket, on sale, with 6% sales tax.
Answer provided by our tutors
Regular price: $40
After 15% discount: 40 - 0.15*40 = 40(1 - 0.15) = 40*0.85 = $34
6% sale tax on $34 is: 0.06*34 = $2.04
The total cost of the jacket is: $34 + $2.04 = $36.04.
