Answer this question:There is a very large room that has 4 tables, 1 sofa and 2 chairs that have 4 legs each. There are also 3 tables with 3 legs each, 1 table with 1 leg, and 1 rocking chair with 2 legs. How many legs are there in the room?
There are 4 tables, 1 sofa and 2 chairs that have 4 legs each so 4 + 1 + 2 = 7 pieces of furniture. These 7 pieces have 4 legs each so they have 7 * 4 = 28 legs. There are 3 tables with 3 legs each so they have 3 * 3 = 9 legs. We have 28 legs and 9 legs as well a 1 leg on a table and 2 on a rocking chair for a total of 28 + 9 + 1 + 2 = 40 legs.
The answer is 40.

Answer this question:Erwan went on shopping. He purchased a pair of shoes at $200 but discounted 30%, and two shirts at $80 each. Upon checkout, the cashier said that there is an additional 5% discount. How much did he spend after all the discounts?
The total discount of a pair of shoes is $200 x 30 / 100 = $60. He spent $200 - $60 = $140 for a pair of shoes. The total cost of two shirts is $80 x 2 = $160. The initial cost of his purchase is $140 + $160 = $300. He got an additional $300 x 5 / 100 = $15 discount upon checkout. Therefore, Erwan spent $300 - 15 = $285 after all the discounts.
The answer is 285.
