the cost of 15 chairs and 2 tables is 8000 if 4 tables cost as much as 10 chairs find the cost of 3 tables and 12 chairs

Let the price of a chair be C and that of a table be T.

So, as per the problem, 10C=4T

or, T=2.5C

Again, 15C+2T=4000

Replacing T by 2.5 C, 15C+2(2.5C)=4000

or, 20C=4000

or C=200

So, the price of 1 chair is 200

The price of a table is T=2.5C=500

So, 12C+3T=12*200+3*500=3900

Answer is 3900

i remember a kid from africa moved to our school and she didn't speak no english. well she did but it was very limited but all the kids including me would ask her question like has she ever hunted a elephant or ever been hunted by a lion. to us she was so interesting even thought she was ordinary but by the fact she was from a different country we thought things were different. (honestly i asked her if she lived in a mud house on the savanna.) do i feel bad about approaching her yeah but do i feel bad about asking her question no because i would have never found out all the cool things about africa that aren't true
