The table shows how much a store charges for certain numbers of pencils. Number of pencils (p) Cost (c) 4 $0.72 7 $1.26 12 $2.16
Arada [10]
Find the rate of change, (y2-y1)/(x2-x1), from the data given...

(2.16-1.26)/(12-7)=0.18

(1.26-0.72)/(7-4)=0.18

Since the rate is constant, this is a linear equation of the form y=mx+b.  Furthermore, since 0 pencils cost 0, b=0, so the cost of the pencils is simply the number of pencils times 18 cents...

c(p)=0.18p  (cost with respect to pencils is 0.18 times the number of pencils)

The average speed is:

\var{v}=75\: miles/h

Step-by-step explanation:

The average speed equation is given by:

\var{v}=\frac{\Delta x}{\Delta t}

Were:

  • Δx is the displacement (225 miles)
  • Δt is the change in time (3 hours)
