A forest has 5 species of mammals: 12 deer, 8 squirrels, 20 rabbits, 4 foxes and 6 bats. How many mammals are there in total? If 70% of them are herbivores, how many herbivores are there?

Step-by-step solution

1. Add the numbers of each species: 12+8+20+4+6 = 50 mammals in total.
2. Compute 70% of 50: 0.70 × 50 = 35 herbivores.
3. Thus there are 50 mammals and 35 herbivores.
