Solve:
the total cost (c) in dollars for building an office of x square feet is given
by the function c(x) = 107,500 + 150x.
if the total cost was $385,000.00, how many square feet was the office?

x=1850

Step-by-step explanation:

C(x) is a stand-in for total cost

since we are given the total cost we can replace the variable with its value

385000=107500+150x

now all we have to do is solve

start by subtracting 107500 from both sides

385000=107500+150x

277500=150x

now we finish solving by dividing both sides by 150

277500=150x

x=1850

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
