You are tiling a 1 square metre bathroom with 10cm square tiles. The exact number of the tiles needed is yet unknown because you
may break some tiles and will have to cut some of them to fit around the corners. Therefore, you work to the rule of thumb that you should buy enough tiles to cover specified area plus 10%. Derive a linear equation for the cost of y for the number of tiles x to be bought. The correct linear equation is?
No, no value for x will result in you getting the same amount of money I.e. on the first day if x =2 you earn 33. on the second day you would've earned 44. Of course this may be wrong so best to double check
