My question is: A shopping center sells T-shirts at $8 each, a sweater at $18, and a jacket at $80. The jacket is on sale with a 10% discount. The sales tax is 5%. Kevin wants to buy six T-shirts, four sweaters, and five jackets for his children. How much does Kevin have to pay for all the items, including the sales tax? Your thoughts:
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. The final answer: 504.
