Question

You spend 2/5 of your money on lunch. Your friend then pays you back a loan of $5.50. Later that day you spend $9.75 on a movie ticket and $4.50 on a snack. You have $12.65 left. How much money did you have before lunch?

Answer 1

Money before spending on lunch = 36 dollars

Explanation:

Let the total money be X

Money spent on lunch
`(2)/(5) X`

Money received from friend
`= 5.50` dollars

Money spent movie ticket
`= 9.75` dollars

Money spent on snacks
`= 4.50` dollars

Money left
`= 12.65` dollars

`(X - (2)/(5)X- 9.75 -4.50+5.5) = 12.65`

`(3)/(5) X`
`= 12.65 + 9.95 +4.50 -5.5`
`= 21.6\\`

X
`= 36`

Money before spending on lunch = 36 dollars
