Answer:

30 geckos

Explanation:

Write and solve an equation of ratios:

geckos g 3

-------------- = ---------------- = ------

lizards 80 - g 5

This is true because the sum of the number of geckos and the number of lizards is 80.

Cross-multiplying: 5g = 240 - 3g. Combining like terms, we get 8g - 240.

Thus, g = the number of geckos = 30

Note that the number of lizards and geckos together is 80. Subtracting 30 from 80 yields 50, the number of anole lizards.
