Answer:
54 pence
Step-by-step explanation:
Definition of the given variables:
- c = total cost (in pence).
- n = number of apples.
- y = cost per apple (in pence).
Therefore, the formula using the defined variables is:
[tex]\large\boxed{c=ny}[/tex]
Given values:
Substitute the given values into the derived formula and solve for c:
[tex]\implies c=6 \times 9[/tex]
[tex]\implies c=54[/tex]
Therefore, the total cost of 6 apples at 9 pence each is 54 pence.
