3750C=100\left(15000-C\right)
Variable C cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by C.
3750C=1500000-100C
Use the distributive property to multiply 100 by 15000-C.
3750C+100C=1500000
Add 100C to both sides.
3850C=1500000
Combine 3750C and 100C to get 3850C.
C=\frac{1500000}{3850}
Divide both sides by 3850.
C=\frac{30000}{77}
Reduce the fraction \frac{1500000}{3850} to lowest terms by extracting and canceling out 50.
