Lavania is studying the growth of a population of fruit flies in her laboratory. after 6 days she had nine more than five times as many fruit flies as when she began the study. if she observes 20 fruit flies on the first day of the study, write and evaluate an expression to find the population of fruit flies lavania observed after 6 days

Lavania observed 39 fruit flies after 6 days of observation

Step-by-step explanation:

Let x be the number of fruit flies on the first day of Lavania's study.

After 6 days she had nine more than five times as many fruit flies as when she began the study.

Five times as many fruit flies as when she began the study = 5x

Nine more than five times as many fruit flies as when she began the study=5x+9

The expression to find the population of fruit flies Lavania observed after 6 days is 5x+9

If she observes 20 fruit flies on the first day of the study, then x=6, then
