Answer:

30 geckos

Step-by-step 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.
