Let’s work through this step by step.
We are told:
> “Suppose we pay 1 dollar for the following items. Calculate the change in each case.”
And we’re given a formula:
>
Change money = paid money - bill
Since we’re paying with
1 dollar, and all prices are in
cents, let’s convert 1 dollar to cents:
→ 1 dollar = 100 cents
So, for each item, we subtract its price (in cents) from 100 cents to find the change.
---
1. Chocolate = 24 cents
Change = 100 - 24 =
76 cents
2. Soap = 40 cents
Change = 100 - 40 =
60 cents
3. Brush = 80 cents
Change = 100 - 80 =
20 cents
4. Milk = 50 cents
Change = 100 - 50 =
50 cents
All calculations checked — they’re correct.
Final Answer:
Chocolate: 76 cents, Soap: 60 cents, Brush: 20 cents, Milk: 50 cents
