Question

Mike had $36 dollars. He spent 1/3 of his money for a moive and 2/9 for a sandwich and drink. How many dollars did Mike spend for the sandwich and drink?Does he have enough money left to buy a book for $18?

Answer 1

We are given that Mike has $36, if he spends 1/3 of this amount, the amount spent is the product of 36 and 1/3, that is:

`\begin{gathered} A_1=36*(1)/(3) \\ A_1=12 \end{gathered}`

Therefore, he spends $12 on the movie.

Now we are told that he spends 2/9 of the money, therefore, he spent:

`\begin{gathered} A_2=36*(2)/(9) \\ A_2=8 \end{gathered}`

In total, he spent $8 on the sandwich.

The money he has left is:

`36-12-8=16`

Therefore, he can't buy an $18 dollars book.
