Answer:

The answer to your question is 48 chairs

Step-by-step explanation:

Data

5 rows- 3 chairs left over

3 rows - 21 chairs left over

Process

1.- Write two equations each for each situation

x = number of rows

y = number of chairs

Equation 1       y = 5x + 3

Equation 2      y = 3x + 21

2.- Solve the system by equality

                      5x + 3 = 3x + 21

                       5x - 3x = 21 - 3

                               2x = 18

                                 x = 18/2

                                 x = 9

3.- Find the total number of chairs

y = 5(9)+ 3                         y = 3(9) + 21

y = 45 + 3                          y = 27 + 21

y = 48                                y = 48

4.- Conclusion

There are 48 chairs

Profit is the amount of money that remains after all expenses of a project have been paid. The year has just​ ended, and Ajax​ C
lilavasa [31]

Answer:

the Profit earned by the company is $280,489

Step-by-step explanation:

Total Cost of 5 projects awarded = $7,435,000

Cost of Project​ 1 = $1,245,000

Cost of Project​ 2 = $985,689

Cost of  Project​ 3 = $1,723,000

Cost of Project​ 4 = $2,567,054

Cost of Project​ 5 = $633,768

We need to find the profit earned by the company.

First we need to find Total cost spent on all 5 projects.

It can be found by adding cost spent on all projects.

Total cost spent on all 5 projects = Cost of Project 1 + Cost of Project 2 + Cost of Project 3 + Cost of Project 4 + Cost of Project 5

Total cost spent on all 5 projects = $1,245,000+ $985,689 + $1,723,000+ $2,567,054 + $633,768

Total cost spent on all 5 projects = $7,154,511

Now we can calculate profit earned using formula:

Profit earned = Total Cost of 5 projects awarded - Total cost spent on all 5 projects

Profit earned = $7,435,000 - $7,154,511

Profit earned = $1,280,489

So, the Profit earned by the company is $280,489
