Answer:
$58,560
Step-by-step explanation:
First step: set up your proportion equation. Keeping the percents on the bottom, I set it up as $48,000/100% = $x/122%. I'm writing it as 122% rather than 22% so we don't have to add the increase in price to the original price later. You can see that, in order to get from 100 to 48,000, you need to multiply by 480, so you can do this to 122 to get x. Your teacher might, instead, want you to cross multiply. Do what's expected of you. Either way, your result should be $58,560. Check that it makes sense by checking that it's an increase and that it looks reasonable for the amount of the increase and you're done.
Answer:
2172 is the total cost
Cost for tiles: 1800
cost of paint: 372
Find the surface area of the wall without floor:(for cost of paint)
40 x 15 + 40x3x2 + 15x3x2 = 600 + 240 + 90 = 930
Cost: 930/25 x 10 = 372
Find area of floor:(to find cost of tiles)
40 x 15 = 600m^2
cost: 600 x 3 = 1800pounds
add them if needed
Hope this helps
Good Luck
