4. Graph the function you found. Suggested units for x are tens and fives for C.Your gas company charges different rates for the amount of gas you use. Suppose you are charged a monthly fee of $20. In addition, you are charged $.35 per therm for the first 50 therms and $.25 per therm for all amounts over 50 therms. 1. Determine the cost if you use 50 therms. $20+$17.50=$37.50 2. Determine the cost if you use 100 therms. 20+$17.50+$12.50=$50.00 3. If C is the monthly charge for x therms, write a piecewise function that expresses C as a function of x. Simplify your answer. $20+$0.35x for x50
