A 3-pack of boxes of juice costs $1.09. A 12-pack of boxes costs $4.39. A case of 24 boxes costs $8.79. Which is the Best Buy? Explain your reasoning!

Respuesta :

simply, check how many times the juices go into the quantity, namely for example, how many times 24 go into 8.79 and so on, to see how much does each juice cost, and thus which is cheaper.

[tex]\bf \cfrac{1.09}{3}\implies \boxed{0.363}333\overline{3} \\\\\\ \cfrac{4.39}{12}\implies \boxed{0.365}8333\overline{3} \\\\\\ \cfrac{8.79}{24}\implies \boxed{0.366}25[/tex]

should be obvious above, I'd think.
