A car has a value of £500 The car loses £80 of its value each month.
Answer
The car starts at £500 and decreases by £80 each month. So A = £500 (0 months), B = £420 (1 month), C = £340 (2 months), and D = £260 (3 months).
Explanation
What the table is showing
You are given a starting value (£500) and a fixed monthly decrease (£80). The table entries A, B, C, and D are just the car’s value after 0, 1, 2, and 3 months.
Subtract £80 each month
Start at month 0, then subtract £80 for each month passed:
- Month 0: $500$
- Month 1: $500 - 80 = 420$
- Month 2: $420 - 80 = 340$
- Month 3: $340 - 80 = 260$
Fill in A, B, C, D
So the missing values are:
- $A = £500$
- $B = £420$
- $C = £340$
- $D = £260$
Quick check using a formula
A simple linear rule is $V = 500 - 80m$, where $m$ is months passed.
- For $m=3$: $V = 500 - 80\cdot 3 = 500 - 240 = 260$, matching D.
