3% for benefits, 3% for energy, and 4% for maintenance and supplies. The new budget calls for $32.2 milion dollars.

what is the dollar amount for this years budget?

Solution

1)

3 minute review =100*3/60= 5%

Commercials took 30% so total time left for new development is :100-30-5=65%

2)

A)

Last year\'s budget is: (1+25/100)15000000=1.25*15000000=18750000

This year\'s budget is:(1+12/100)18750000=21000000

B) This year\'s budget is not 37% of the budget as the percent increase was not on two separate years so it gets multiplied not added.

Total increase for next years budget is: (5+3+3+4)=15% increase

Hence next year\'s budget is: 24150000 =24.15 million dollars
