Can some one check this for me..please...
The customer wishes to buy a carpet 12.5 sq metres. The cost $C of supply and fitting the carpet has a price of $p per square metre and is given by the formula
C= 75 + 12.5P
Rearrange this formula to make P the subject ...
In order to make P the subject of the equation,
P = 75 - C/12.5
If a customer had a budget of $500.00 then the maximum price of carpet a square metre he can afford ????
where P = 75 - C / 12.5
500 - 75 / 12.5 = 34
Therefore the buyer could afford to spend $34.00 per square metre on carpet.
If i am wrong please show me where...thanks
