What in disguise???

1. Max and Roy each had some money.
If Max spent $60 each day and Roy spent $40 each day, Max would have $80 left when Roy had spent all his money.
If Max spent $30 each day and Roy spent $80 each day, Max would have $890 left when Roy had spent all his money.
How much did Roy have ?

2. Amy and Billy were given some money each. If Amy spent $25 each week and Billy spent $75 each week, Amy would still have $1350 left when Billy had spent all his money. If Amy spent $75 each week and Billy spent $25 each week, Amy would still have $150 left when Billy had spent all his money.

How much money did Amy receive?


3. 20% of Dominic’s savings was $120 more than 1/4 of Joshua’s savings.
After Dominic spent 5/6 of his savings and Joshua spent 50% of his savings, Dominic had $30 more than Joshua.
Find Dominic’s savings at first.
