Let’s solve each problem one by one.
---
Problem 1:
> Father divides the interest from his savings of $93 equally among his 3 children. How much does each child get?
Wait — this is tricky. The problem says “the interest from his savings of $93”. But it doesn’t say how much interest he earned. It just says “savings of $93”. That might be a mistake in the wording. In many elementary math problems, when they say “divides the interest from his savings of $X”, they often mean he has $X to divide — especially if no interest rate or amount is given.
So let’s assume the problem meant:
> Father has $93 and divides it equally among his 3 children.
That makes sense for a basic division problem.
Step-by-step:
- Total money = $93
- Number of children = 3
- Divide: 93 ÷ 3 = ?
Let’s calculate:
3 × 30 = 90 → remainder 3
3 × 1 = 3 → so 30 + 1 = 31
✔ So each child gets $31.
*(Note: If we take the problem literally as written — “interest from savings” — we can’t solve it without knowing how much interest was earned. Since this is likely a typo or simplified wording, we go with dividing $93.)*

Problem 2:
> It costs Chris $4.15 to post two parcels. One parcel costs $3.25 to post. How much does the other parcel cost to post?
This is subtraction.
Total cost = $4.15
Cost of first parcel = $3.25
Cost of second parcel = Total – First = 4.15 – 3.25
Let’s subtract:
```
4.15
– 3.25
-------
0.90
```
✔ So the other parcel costs $0.90.

Problem 3:
> Doris buys a book for $131.30 and a magazine for $22.80. How much does she spend altogether?
Addition:
$131.30 + $22.80
Align decimals:
```
131.30
+ 22.80
---------
154.10
```
Step-by-step:
- 0 + 0 = 0 (hundredths)
- 3 + 8 = 11 → write 1, carry 1 (tenths)
- 1 + 2 + 1 (carry) = 4 (ones)
- 3 + 2 = 5 (tens)
- 1 + 0 = 1 (hundreds)
✔ Total = $154.10

Final Answer:
1. $31
2. $0.90
3. $154.10
