$330
Step-by-step explanation:
What is mean/average?
It is the "sum of all the numbers" divided by the "number of numbers".
An average of 200 for 6 numbers means:
THus, if we were to add the 6 numbers, we would get "1200". Let the 6th number be x, so we can write:
120 + 110 + 200 + 300 + 140 + x = 1200
870 + x = 1200
x = 1200 - 870
x = 330
To make the average $200, Pedro needs to make $330 on 6th day.
