The number of hours, t, it takes a boat to travel 15 miles upstream is represented
iogann1982 [59]

The equation of c is an illustration of subject of formula

The equation of c in terms of r and t is c = r - 15/t

<h3>How to determine the equation?</h3>

The equation is given as:

t = 15/(r - c)

Cross multiply

t(r - c) = 15

Divide both sides by t

r - c = 15/t

Subtract r from both sides

-c = -r + 15/t

Multiply both sides by -1

c = r - 15/t

Take LCM

c = \frac{rt - 15}{t}

Hence, the equation of c in terms of r and t is c = \frac{rt - 15}{t}

Property in Dry Gultch County is assessed at $305,000,000. The taxes to be raised are $13,750,000. What is the tax rate?
yanalaym [24]
Well you know that the value is 305 million
And the taxes are 13.75 million. taxes are a percentage of the value. to get a percentage of the value you use :
value * percent = percentage of value

So:
305 million * percent = 13.75 million
or:
305 * x = 13.75
x = 13.75 / 305
x = .045

x = 4.5%
