Complete the table by calculating the missing values (amount and quantity where applicable).



Answer :

Let's complete the table by calculating the missing values.

| Tool / Equipment | Price per item (including 15% VAT) | Number required | Cost (R) |
|--------------------------------------------------|------------------------------------|-----------------|----------------|
| Glue Gun | Not Provided | 5 | Not Provided |
| Glue sticks 1 kg | R 160 | 14.5 | 2320 |
| Battery pack of 60 (Penonsing batteries) | R 199 | 2 | 398 |
| Battery holder | R 12.88 | 60 | 772.80 |
| LED (pack of 300) | R 199 | 1 | 199 |
| Buzzer | R 13.23 | 20 | 264.60 |
| Connecting wire per m | Not Provided | 20 | 51.80 |
| Resistor (pack of 10) | R 76 | 10 | 760 |
| Paint per litre | Not Provided | 3 | 477 |
| | Total | | 4845.20 |

Step-by-step explanation:

1. Glue Gun: The price per item is not provided.

2. Glue sticks 1 kg:
- Given the cost of R 2320 for the glue sticks and the price per kg as R 160:
- Number of kg required: [tex]\( \frac{2320}{160} = 14.5 \)[/tex]

3. Battery pack of 60 (Penonsing batteries):
- Given the price per pack is R 199 and 2 packs are required:
- Total cost: [tex]\( 199 \times 2 = 398 \)[/tex]

4. Battery holder:
- Given the total cost of R 772.80 and the price per holder as R 12.88:
- Number required: [tex]\( \frac{772.80}{12.88} = 60 \)[/tex]

5. LED (pack of 300):
- Given the price per pack is R 199 and 1 pack is required:
- Total cost: [tex]\( 199 \times 1 = 199 \)[/tex]

7. Buzzer:
- Given the total cost of R 264.60 and the price per buzzer as R 13.23:
- Number of buzzers required: [tex]\( \frac{264.60}{13.23} = 20 \)[/tex]

8. Connecting wire per m:
- The price per meter is not provided, only the total cost and total meters are given:
- Given 20 meters required and total cost R 51.80

9. Resistor (pack of 10):
- Given the price per pack is R 76 and 10 packs are required:
- Total cost: [tex]\( 76 \times 10 = 760 \)[/tex]

10. Paint per litre:
- The price per litre is not provided; given 3 litres required and total cost R 477.

11. Total:
- Summing up all individual total costs:
- [tex]\( 2320 + 398 + 772.80 + 199 + 264.60 + 51.80 + 760 + 477 = 4845.20 \)[/tex]
