Penny Activity

Independent variable is the months; dependent variable is number of quarters

Yes, the number of quarters seems to be going up in a steady rate of change.

The slope is 27; this means that each month, Penny increases the number of quarters in her jar by 27.

NEXT = Now + 27; starting at 158 

y = 27x + 158

There were 158 quarters in the jar when her grandmother gave her the jar.

Penny would have 1130 quarters on her 18th birthday.
