Gre4nikov [31]

A system of equations is good for a problem like this.
Let x be the number of student tickets sold
Let y be the number of adult tickets sold
x + y = 200
2x + 3y = 490
x = 200 - y
2(200 - y) + 3y = 490
400 - 2y + 3y = 490
400 + y = 490
y = 90
The number of adult tickets sold was 90.
x + 90 = 200 --> x = 110
2x + 3(90) = 490 --> 2x + 270 = 490 --> 2x = 220 --> x = 110
The number student tickets sold was 110.

AnnZ [28]

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.
