Kevin ya so samun shida T-shirts shida, sweaters hudu, da kuma jackets biyar ga yara yake. Me yasa Kevin ya yi bayar da duk abubuwan, kamar yadda aka samu a shan shan? <response>: The six T-shirts cost 6 x $8 = $48.
The four sweaters cost 4 x $18 = $72.
And five jackets normally cost 5 x $80 = $400.
So, a discount of 10/100 x $400 = $40 for the five jackets.
Thus, the selling price of the five jackets is $400 - $40 = $360.
Hence, the total cost of all the items is $48 + $72 + $360 = $480.
The sales tax is equal to 5/100 x $480 = $24.
Therefore, Kevin has to pay $480 + $24 = $504. including the sales tax.

Answer is 504.
