To find out how much money Alex had in the beginning, we can follow these steps:
Step 1: Calculate the amount of money Alex had left after spending 3/7 of his money.
To do this, subtract 3/7 of his money from the whole amount:
Remaining money = (1 - 3/7) * Initial amount
Step 2: Calculate the amount Alex gave to his sister, which is 1/4 of the remainder.
To do this, multiply the remaining money by 1/4:
Amount given to sister = Remaining money * 1/4
Step 3: Subtract the amount given to his sister from the remaining money to find out Alex's final amount.
Final amount = Remaining money - Amount given to sister
Step 4: Since the final amount is $120, we can set up an equation and solve for the initial amount.
Final amount = $120
Therefore, we have:
Remaining money - Amount given to sister = $120
Now let's calculate the initial amount.
