Answer:
50 bats total
Step-by-step explanation:
To solve this problem, all one has to do is, set up a proportion, remember, a proportion is;
[tex]\frac{part}{whole} = \frac{percent}{100}[/tex]
In this case;
[tex]\frac{hits}{total.bats} = \frac{percent}{100}[/tex]
It is given that;
percent - 60%
hits - 30
Now substitute in the values and solve;
[tex]\frac{30}{total.bats} = \frac{60}{100}[/tex]
Solve, first simplify;
[tex]\frac{30}{total.bats} = \frac{3}{5}[/tex]
Now use cross products;
150 = 3(total_bats)
Inverse operations;
150 = 3(total_bats)
/3 /3
50 = total_bats
