Answer:
The required expression is 4d.
Explanation:
It is given that you are paid $4 for each day you work. It means
Earnings = $4 for each day of work
Let d be the number of days you work in a month.
The formula for total pay is
Total pay= Pay for each day × Number of days
Total pay = 4 × d
Total pay = 4d
It meas total pay is 4 times of the number of working days.
Therefore the expression 4d represent the total pay for that month in dollars.
