Part One: The employees must sell 72 pizzas in order to receive bonus.

Part Two: There is a 10% increase in the sales.

Step-by-step explanation:

Given,

Pizzas sold yesterday = 60

(part one) The owner offers the employees a bonus if the number of pizzas sold increases by 20% today. How many pizzas must the pizzeria sell for employees to receive the bonus?

Sales to increase = 20% of yesterday sales

Sales to increase = $\frac{20}{100}*60 = 12\ pizzas$

Total = Pizzas sold yesterday + Sales to increase

Total = 60+12 = 72 pizzas

The employees must sell 72 pizzas in order to receive bonus.

(part two) Suppose the actual number of pizzas sold today was 66. Describe the number of pizzas sold as a percent increase or decrease, rounded to the nearest hundredth.

Number of pizzas sold = 66

Difference = Pizzas sold today - Pizzas sold yesterday

Difference = 66-60 = +6

The positive sign indicates the increase in sales.

Increase percent = $\frac{Difference}{Pizzas\ sold\ yesterday}*100$

Increase percent = $\frac{6}{60}*100 = \frac{600}{60}$

Increase percent = 10%

There is a 10% increase in the sales.

Step-by-step explanation:

This explanation mostly depends on what you're learning right now. The first way would be to convert this matrix to a system of equations like this.

g + t + k = 90

g + 2t - k = 55

-g - t + 3k = 30

Then you solve using normal methods of substitution or elimination. It seems to me that elimination is the quickest method.

g + t + k = 90

-g - t + 3k = 30

____________

0 + 0 + 4k = 120

4k = 120

k = 30

No you can plug this into the first two equations

g + t + (30) = 90

g + t = 60

and

g + 2t - (30) = 55

g + 2t = 85

now use elimination again by multiplying the first equation by -1

g + 2t = 85

-g - t = -60

_________

0 + t = 25

t = 25

Now plug those both back into one of the equations. I'll just do the first one.

g + (25) + (30) = 90

g = 35

Therefore, we know that Ted spent the least amount of time on the computer.

The second method is using matrix reduction and getting the matrix in the row echelon form, therefore solving using the gauss jordan method. If you would like me to go through this instead, please leave a comment.
