With black ink      ⇒⇒⇒ <span>b(t)=152-33t
With </span>colored ink   ⇒⇒⇒ <span>c(t)=152-30t

After 1 minute :
b = 152 - 33 * 1 = 152 - 33 = 119
c = 152 - 30 * 1 = 152 - 30 = 122
c - b = 122 - 119 = 3

The correct choice is:
</span><span>G. The printer prints 3 fewer pages per minute in black ink than in colored ink.</span>

Each hour it grows 14%. This means after 1 hour, it has grown 7*1.14. After two hours 7*1.14 (1.14) or 7*(1.14)^2, etc so after 22 hours use equation above to solve.

Please show steps when solving this.
defon

\frac{240 inches}{1 minute}

We're going to change one unit at a time. Let's start with inches to feet. There are 12 inches in 1 foot. Divide 240 by 12 or multiply by 1/12.

\frac{240 inches}{1 minute} * \frac{1 foot}{12 inches}=\frac{20 feet}{1 minute}

Next, let's do the time using the same idea. Remember that there are 60 minutes in 1 hour.

\frac{20 feet}{1 minute} * \frac{60 minutes}{1 hour} = \frac{1200feet}{1hour}

Answer: 1200 feet per hour

Hope this helps!
