Answer 2

Sweater is least expensive in City C with 2.9% sales Tax

Cost of Sweater in city B is $31.23

Explanation:

Cost of a sweater = $30

Sales tax in city A= 3%

Cost in City A = $30 + ($30*3%)

= $(30 +0.9)=$30.9

Sales tax in City B = 4.1%

Cost in City B = $30+($30*4.1%)

= $(30+1.23)=$31.23

sales tax in city C = 2.9%

Cost in City C = $30+($30*2.9%)

=$(30+0.87)=$30.87
