Question

You and your friends have put your money together and have $12 to spend on lunch. You agree to share a large fry and buy hamburgers with the rest of the money. If the price of a large fry is $1.22 and the price of a hamburger is $0.89, how many hamburgers can you buy?

Answer 1

We know that

• A large fry costs $1.22.

,

• A hamburger costs $0.89.

,

• The total money is $12.

,

• They buy 1 large gry.

Based on the given information, we have

`1.22+0.89h=12`

Now, we solve for h to find the number of hamburgers they can buy

`\begin{gathered} 0.89h=12-1.22 \\ 0.89h=10.78 \\ h=(10.78)/(0.89) \\ h\approx12 \end{gathered}`

Hence, they can buy 12 hamburgers in total.
