Answer:
The mother is 3d older than the daughter
Step-by-step explanation:
Given
Represent the mother's age with m
and
The daughter's age with d
Required
Determine how much older is the mother
First, we need to calculate the mother's age
[tex]m = 4 * d[/tex]
[tex]m = 4d[/tex]
Next, we calculate their age difference
[tex]Age\ Difference = m - d[/tex]
Substitute 4d for m, we have:
[tex]Age\ Difference = 4d - d[/tex]
[tex]Age\ Difference = 3d[/tex]
Hence, the mother is 3d older than the daughter
