Final answer:
Elise will make $931.50 over the 3 days.
Step-by-step explanation:
To calculate how much money Elise makes over the 3 days, we need to find the total number of calls she made and multiply it by the amount she earns per call. We can do this by summing up the total calls she made on each day and then multiplying it by $1.50.
So, the total number of calls Elise made is 247 + 218 + 156 = 621 calls.
Therefore, Elise will make $1.50 x 621 = $931.50 over the 3 days.
