Lizzy: In a shopping mall, one T-shirt costs $20 each; a pair of pants costs $80; a pair of shoes costs $150. All items will get a 10% discount. How much does Eugene have to pay if he buys four T-shirts, three pairs of pants, and two pairs of shoes?.
Me: Hmmm, let me think. I think this is the detailed solution:
User
The total cost of the four T - shirts is 4 x $20 = $80. Three pairs of pants cost 3 x $80 = $240. Two pairs of shoes cost 2 x $150 = $300. The total amount of all the items is $80 + $240 + $300 = $620. Thus, Eugene will get a discount of 10 / 100 x $620 = $62. Therefore, Eugene will have to pay $620 - $62 = $558. Final answer: 558.
