Question

If I am buying cakes which is the better option.

You can get 7 cakes for $182 or 5 cakes for $143.

Explain why that is the better choice.

Answer 1

To find which one is better, we can find the unit cost for both of them:


`(182)/(7) = (x)/(1)`

`x=26`


`(143)/(5) = (x)/(1)`

`x = 28.6`

This shows that the first deal is better because it costs less money.
