Carrie applied for an after-school job
at the local market. Carrie asked for
$2 an hour, but the boss proposed
giving the $0.10 for the first hour,
$0.20 for the second hour, $0.40 for the
third hour, $0.80 for the fourth hour
and so on. Below is a table of the hours
worked per week and the pay for each
hour for each of the two pay plans.

The equation y = 0.002x + 4.75 models the
total cost in dollars, y, of using a 20-watt
compact fluorescent light bulb for x
hours. The table models the cost of using
a 60-watt incandescent light bulb.
Based on the information given in
question 63, determine which light bulb
will cost the least amount to use. Be sure
to include which costs the least for a small
number of hours used and which costs the
least for a large number of hours used.
They cost the same ($6.75) for 1,000 hours
of electricity.
If you use less than 1,000 hours then the
60-watt incandescent light bulb is cheaper.
If you use more than 1,000 hours then then
20-watt fluorescent bulb is cheaper.

The table represents the volume of ink
remaining in an inkjet printer cartridge.
Which solution represents the number of
hours of use when the costs of using the
two light bulbs are the same?
A 600 hours
B 688 hours
C 1000 hours
D 1148 hours
What do the x- and y-intercepts of the
graph of these data represent?
Explain your answer.
The x-intercept is the number of pages the
printer prints before running out of ink,
which is 500 pages.
The y-intercept is the starting amount of ink
in the printer, which is 25 ml.
