Question

Janelle can get a 24 pack of bottled water for $6.80. HJow much would Janelle have to pay for a 12 pack of bottled water if the ratios are proportional?

Answer 1

make a ratio of cost/# of bottles
\[ \frac{6.80}{24}\]
and another ratio: unknown cost / 12 bottles \( \frac{x}{12}\)
and set the ratios equal
\[ \frac{6.80}{24} = \frac{x}{12} \]
can you solve this ?
