Barbara saw her favorite band, Royal Gems, perform on Friday night. She paid $77.50 for a ticket to the show. She also had to pay for the 4 hours her car was parked in the parking garage. Barbara spent a total of $89.50. Which equation can you use to find x, how much it cost for each hour Barbara's car was parked in the garage?

Answer:

cost for each hour her car was parked in garage =  $3

Step-by-step explanation:

Let the cost every hour car parked in garage be x.

4x + $77.50 =  $89.50 4* x because the car had been 4 hours in garage.

4x = $89.50 - $77.50

4x = $12

x =  $12 / 4

x =  $3

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
