margie is certain that every time she parks in the city garage it costs her at least $2.25. If the garage charges 25 cents plus 25 cents for each 1/2 hr, how long is margie's car parked?
i say 5 am i correct?
Nope. Try 4 hours...
To determine how long Margie's car is parked, we first need to understand how the garage charges. According to the information given, the garage charges 25 cents initially plus an additional 25 cents for each half hour.
Let's represent the total cost as C and the time parked in hours as T.
We know that the total cost is at least $2.25, so we can set up an equation:
C ≥ $2.25
Now, we can substitute the formula for the total cost:
C = $0.25 + $0.25 * (2T)
Simplifying this equation, we get:
$2.25 ≥ $0.25 + $0.50T
Now, isolate the variable T:
$2.00 ≥ $0.50T
Divide both sides of the equation by $0.50:
4 ≥ T
So, the car must be parked for at least 4 hours.
Therefore, your answer of 5 hours is correct.
