Let’s solve each problem one by one.

Problem 1:
Nadira has 5 pieces of $10 notes and 7 pieces of $5 notes. How much money does she have?
Step-by-step:
- First, calculate how much the $10 notes are worth:
5 × $10 = $50
- Then, calculate how much the $5 notes are worth:
7 × $5 = $35
- Now add them together:
$50 + $35 = $85
✔ So Nadira has $85.

Problem 2:
Rosie has $28.90. Her father gives her $45 more. Find the total amount of money Rosie has.
Step-by-step:
- Start with what Rosie already has: $28.90
- Add what her father gave: $45.00
Let’s line it up to add:
```
28.90
+ 45.00
-------
73.90
```
✔ So Rosie now has $73.90.

Problem 3:
Toby has $35 to buy a fish aquarium. He received a balance of $7.50 from the shopkeeper. What is the cost of the aquarium?
Step-by-step:
- Toby gave $35 to the shopkeeper.
- The shopkeeper gave back $7.50 as change (balance).
- That means the aquarium cost less than $35 — specifically, the difference between what he paid and what he got back.
So we subtract:
$35.00 - $7.50 = ?
Let’s do it carefully:
```
35.00
- 7.50
-------
27.50
```
✔ So the aquarium costs $27.50.

Final Answer:
1. $85
2. $73.90
3. $27.50
