Question

A city dumps plastic shade balls into a reservoir to prevent water from evaporating during a drought. It costs $5760 for 16,000 shade balls. How much does it cost for 12,000 shade balls?

Answer 1

Step-by-step explanation:

If it costs $5760 for 16,000 shade balls, then it would cost $\frac{5760}{16000}=0.36$ for 1 ball.

So

$0.36*12000=4320$
