Question

The county administrator's office is making plans to finance the next phase of infrastructure repair to the county's roads
and bridges. To help with their planning, they have developed functions that model the anticipated tax money available and
planned budget for repairs, for any given year, x years from today.
The expected tax money, in millions, received from the state is represented by the function 7(x) = 14x³ + 43x² + 37x+ 190.
The planned budget allocating money, in millions, for infrastructure repairs in that same year is represented by the function
R(x) 35x +90.
Which function represents the balance, in millions, that remains in a given year, after using a portion of the tax money to
pay for infrastructure repairs?
DA.
B(x) = 14x³ + 8x² + 37x+100
OB. B(x) = 14x³ + 8x² +37x+ 280
OC. B(x) = 14x³ + 43x² + 2x + 100
OD.
