Answer:
5 hours
Step-by-step explanation:
Lillian is deciding between two parking garages.
Let the time required to park be represented by t
A = Amount
From Garage A
A = the amount Garage A would charge if Lillian parks for t hours
B = the amount Garage B would charge if Lillian parks for t hours.
Garage A
Garage A charges an initial fee of $4 to park plus $3 per hour.
A = $4 + $3 × t
A = 4 + 3t
Garage B charges an initial fee of $9 to park plus $2 per hour.
B = $9 + $2 × t
B = 9 + 2t
The hours parked, t, that would make the cost of each garage the same is calculated by equating A to B
A = B
4 + 3t = 9 + 2t
Collect like terms
3t - 2t = 9 - 4
t = 5 hours
Therefore, the hours parked, t, that would make the cost of each garage the same is 5 hours
Answer:
(1,3)
Step-by-step explanation:
It is the intercept of the two lines
1a) so for this problem, I took what they gave you, 637.5 and divided it by .75 and got 850
so .75 * 850 = the gallons, so just take the number of hours and multiply it by 850 to get your gallons
0.25 x 850 = 212.5
1.5 x 850 = 1,275
2.5 x 850 = 2,125
1b) the unit rate is 850
1c) 5.5 x 850 = 4,675 gallons
1d) So 850 gallons can be filled in an hour, you only need 100 gallons
850/100 = 17/2 (simplified)
17 gallons/hour 60 minutes
------------------------- x ---------------------
2 gallons 1 hour
the gallons cancel out and the hours cancel out which leaves us with:
17 x 60 = 1,020 / 2 = 510
510 minutes
2) I don't know how to do two sorry
