Answer:
- adult: 325
- children's: 225
Step-by-step explanation:
It usually works well to let a variable represent the higher-value item in the mix. Here, we can let 'a' represent the number of adult tickets sold. Then the total revenue is ...
1.50a +1.00(550 -a) = 712.50
0.50a = 162.50 . . . . . . . . . . . . . subtract 550 and collect terms
a = 325
c = 550 -325 = 225
325 adult and 225 children's tickets were sold.
To find the answer, we can first convert all their speed to feet per second.
Also note that:
1 miles = 5280 feet
1 minute = 60 seconds
We can then proceed to find the answer:
Debbie: 10 ft/s
Stephanie: 131/10 = 13.1 ft/s
Jessica: 1x5280/440 = 12ft/s
Ron: 547/1x60 = 9.1166..ft/s
Therefore, Stephanie has the highest speed (13.1 ft/s)
Hope it helps!
