Work Step by Step

Maximum speed permitted on freeways = 65 mi / h Minimum speed permitted on freeways = 40 mi / h Fine for violating these limits is $\$$15 for every mile per hour above maximum speed or below minimum speed. Amount of fine as function F is $F(x)=15(40-x) \ if 0 \ \leq x \lt40$ $F(x)=0 \ if 40 \leq x \leq 65$ $F(x)= 15(x=65) \ if x = 65$
