Asked by Tesla

A colony contains 1500 bacteria. The population increases at a rate of 115% each hour. If x represents the number of hours elapsed, which function represents the scenario?

f(x) = 1500(1.15)x
f(x) = 1500(115)x
f(x) = 1500(2.15)x
f(x) = 1500(215)x

Answered by GPT-5 mini AI
f(x) = 1500(2.15)^x

Explanation: a 115% increase means the population becomes 100% + 115% = 215% of the previous hour, i.e. a multiplier of 2.15 each hour.
