31. REWRITING A FORMULA A common statistic used in
professional football is the quarterback rating. This
rating is made up of four major factors. One factor is
the completion rating given by the formula
R= 5
5C - 0.3)
where C is the number of completed passes and A is
the number of attempted passes. Solve the formula
for C.


Sagot :

Solving for a variable in an equation means that we want to make the variable the subject of the formula. The equation of C is: [tex]C = 0.04R + 0.06[/tex]

Given that:

[tex]R = 5(5C - 0.3)[/tex]

To solve for C, means that we make C the subject.

Divide both sides by 5

[tex]\frac R5 = 5C - 0.3[/tex]

[tex]0.2R = 5C - 0.3[/tex]

Add 0.3 to both sides

[tex]5C = 0.2R + 0.3[/tex]

Divide both sides by 5

[tex]C = 0.04R + 0.06[/tex]

Hence, the equation of C is:

[tex]C = 0.04R + 0.06[/tex]
