Given: Received amount = $18

To Find:

• Difference between the amount of money spent and amount of money saved in a week.
• Tom's saving in a week.

Step-by-step explanation:

Step 1: As we know that Tom received total of $18 from his father. Tom spend and save the given money in a ratio of 5 : 4.

Let Tom save 5x dollar and spent 4x dollar.

Amount save + amount spend = 18

5x + 4x = 18

9x = 18

x = 2

Thus, amount of money save = 5x = $10

Amount of money spent = 4x = $8
