0.07x = 126
mesut collected $126
to find the $126, the total amount must be multiplied by the 7% (0.07)
However, we do not know the total amount,so, the total amount can thus be represented by the variable "x" which then gives us the following equation:
0.07x = 126
0.07 is the percent
x is the total
126 is mesut's amount
1) 0.07x = 126
divide 0.07 with 0.07 (this cancels out)
2) divide 126 by 0.07
3) x = 1800
To check if the answer is correct, simply multiply 1800 with 0.07 which should give you 126.
