Aparking lot charges $1.50 for the first hour of parking, and 55 cents for each additional half hour . how much would it cost to park a car from 12: 45 pm to 6: 15 pm

12:45 pm to 6:15 pm is 5 hours 30 minutes. So you start out with $1.50 for the first hour and $0.55 for additional half hour. So altogether you have 11 half hours. So you would take $0.55 times 11 which gives you $6.05. Then add 6.05 and 1.50 which gives you 7.55. So your answer is $7.55

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
