Answer:

The 2 million bats will consume 20 tons of insects in the city of Austin

Solution:

The population of the bats increases to 2 million in the city of Austin

We have to find about how many insects would they consume?

Now, according to given information

1.5 million bats ⇒ 15 tons of insects

Now, 2 million bats ⇒ x tons of insects

Then by chris cross method


1.5 * x = 15 * 2


x * (15)/(10)=15 * 2


\begin{array}{l}{x * 15=15 * 2 * 10} \\\\ {x=2 * 10=20}\end{array}

Hence, the 2 million bats will consume 20 tons of insects.
