Peter buys 4 apples and x peaches at the market. apples coat $0.55 and peaches cost $0.45. Write a function, f(x), to represent how much money peter spent on apples and peaches
---------------------------------------------------------------------

f(x) = $0.55*4 + $0.45*x in dollars, or

f(x) = 4*55 + x*45 in cents.

Multiply yourself 4*55 . . .
