Answer:
76d + 104d
Step-by-step explanation:
Ellie is charged $76 per day for the pressure washer
Ellie is charged $104 per day for the paint sprayer
The number of days = d
Ellie would be charged 76 * (d) for the pressure washer
Ellie would be charged 104 * (d) for the paint sprayer
If you add them together, it is 76d + 104d
