Question

Pablo needs 9,000 mL of soda for a

class experiment. The grocery store
sells soda for $2 per liter. How much
money does Pablo need to buy the
soda?

Answer 1

`\$18`

Explanation:

Convert milliliters to liters using the conversion
`1,000\:\mathrm{ml}=1\:\mathrm{l}`:

`9,000\text{ ml}=9\text{ l}`.

Since the grocery store sells soda for $2 per liter, Pablo needs
`9\cdot \$2=\boxed{\$18}` to buy the soda.
