Answer:
4 hours
Step-by-step explanation:
Since the initial fee is $90, you will subtract $90 from $330, getting $240. Since every hour after 1 hour is $60, you would divide $240 by $60 getting 4 hours
Ah well this would look like 2(30) + 30 = 90 aka 2L + W = 90
The answer is 19.. substitute -1 into the function whenever you see x put -1 there. This implies that 3+16 =19
