Question

Pedro's Diner is open six days a week. His income for the first five days this week was
$120, $110, $200, $300, and $140. How much must he make on the sixth day to have a
mean(average) of $200.

Answer 1

Pedro must make $330 on the 6th day to have a mean average of $200.

Step-by-step explanation:

Formula for Mean Average

Mean Average = $\frac{Sum of data}{Total number of data}$

DATA:

1st day = $120

2nd day = $110

3rd day = $200

4th day = $300

5th day = $140

6th day = x

Solution:

Mean Average = $\frac{Sum of data}{Total number of data}$

200 = $\frac{120+110+200+300+140+x}{6}$

200*6 = 870+x

1200 - 870 = x

x = 330

Pedro must make $330 on the 6th day to have a mean average of $200.
