Answer:
Step-by-step explanation:
Let x represent the number of years it will take the two colleges to have the same enrollment.
In 2000, there were 12900 students at college A, with a projected enrollment increase of 900 students per year. This means that the expected number of students at college A in x years time is
12900 + 900x
In the same year, there were 25,000 students at college B, with a projected enrollment decline of 700 students per year. This means that the expected number of students at college B in x years time is
25000 - 700x
For both colleges to have the same enrollment,
12900 + 900x = 25000 - 700x
900x + 700x = 25000 - 12900
1600x = 12100
x = 12100/1600
x = 7.56
Approximately 8 years
The year would be 2000 + 8 = 2008
Answer:
$77.4
Step-by-step explanation:
GIVEN: On the trip from KC to Springfield, the church van consumed
gallons of gas to go
miles. If gas cost
per gallon.
TO FIND: Cost of a round trip to Springfield.
SOLUTION:
Distance of springfield from KC ![=179\text{ miles}](https://tex.z-dn.net/?f=%3D179%5Ctext%7B%20miles%7D)
As it is a round trip total distance ![=2\times179=358\text{ miles}](https://tex.z-dn.net/?f=%3D2%5Ctimes179%3D358%5Ctext%7B%20miles%7D)
As
gallons gas used for
miles distance
gas required for
mile
gallons
gas required for
miles
gallons
cost of one gallon of gas ![=\$2.58](https://tex.z-dn.net/?f=%3D%5C%242.58)
cost of
gallons of gas ![=30\times2.58=\$77.4](https://tex.z-dn.net/?f=%3D30%5Ctimes2.58%3D%5C%2477.4)
Hence cost of roundtrip to Springfield is $77.4
