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 2

$4320

Explanation:

If it costs $5760 for 16,000 shade balls, then it would cost
`(5760)/(16000)=0.36` for 1 ball.

Hence to find cost of 12,000 balls, we need to multiply $0.36 with 12,000.

So

`0.36*12000=4320`
