Please help me : Matt is going to walk in a fundraiser event to raise money for his school band. His mother has agree to donate $8 to the school for each mile that Matt walks, plus an additional $100. The function f(x)=8x+100 represents the total money Matt will raise dependent upon the number of miles (x) that Matt will walk.

Part A: Use the function to determine the amount of money Matt will raise if he walks 14 miles. To earn full credit, show your work using a method explained in the Orientation.

Part B: If Matt wants to raise $300 for the band, how many miles will he need to walk? To earn full credit, show your work using a method explained in the Orientation.
