Question

which of the contexts below represents linear growth?
answer
an amusement park charges $3.00 to go on each of the rides.
a population of 150 bacteria quadruples every hour.
a coin collection appreciates at a rate of 2.7% per year.
snow was melting at a rate of 2.5 inches per hour.
submit answer

Explanation:

Linear growth occurs when a quantity changes by a constant amount over equal intervals of time.

1. The amusement park ride charge is a fixed per-ride cost, not a growth over time.
2. Bacteria quadrupling every hour is exponential growth (multiplicative change).
3. A coin collection appreciating by a percentage per year is exponential growth.
4. Snow melting at a constant 2.5 inches per hour is a constant amount of change over equal time intervals, fitting linear growth.

Answer:

Snow was melting at a rate of 2.5 inches per hour.
