Please tell me if the answers I posted are correct with the questions given. I am terrible at math.

A certain Metropolitan area is building a new Performing Arts Center with two auditoriums to be used as concert venues.

Budget: $89,200,000 for construction costs
$5,300,000 for purchase of the land

What integer would represent the total cost of the project?
94,500,000

Thirty-seven percent of the construction costs will be used for labor. Write an algebraic expression that indicates how much money will be spent on labor. Do not solve.
37%∙89,200,000=x, or .37∙89,200,000=x

How much money will be spent on labor? Show how you arrived at your answer.
33,004,000: 37/( 100)∙x/89,200,000=33,004,000 ,or 0.37∙89,200,000=33,004,000

At the completion of the project, it was determined that the project exceeded the budget by 2%.

How much additional money did the project cost? Show how you arrived at your answer.
96,390,000 2/100∙x/94,500,000=1,890,000 94,500,000+1,890,000 = 96,390,000

What was the final cost of the project? Show how you arrived at your answer.
The final cost was 96,390,000. The above answer tells how I arrived at this solution.
