Anastasia uses the equation p = 0.7(rh + b) to estimate the amount of take-home pay, p, for h hours worked at a rate of r dollars per hour and any bonus received, b.What is an equivalent equation solved for h?
p = 0.7 ( r h + b )
p = 0.7 r h + 0.7 b
0.7 r h = p - 0.7 b
h = ( p - 0.7 b ) / 0.7 r
h = 10 ( p - 0.7 b ) / 7 r
h = ( 10 p - 7 b ) / 7 r
Answer:
\(h=\frac{p-0.7b}{0.7r}\)
Step-by-step explanation:
The equation given is \(p=0.7(rh+b)\)
Using distributive property on this, we can expand. Distributive property is given as:
\(a(b+c)=ab+ac\)
Using this, we have:
\(p=0.7rh+0.7b\)
Rearranging and solving for \(h\) gives us:
\(p-0.7b=0.7rh\\\frac{p-0.7b}{0.7r}=h\)
This is the formula with \(h\) as the subject.
