Answer: the tuition in 2020 is $502300
Step-by-step explanation:
The annual tuition at a specific college was $20,500 in 2000, and $45,4120 in 2018. Let us assume that the rate of increase is linear. Therefore, the fees in increasing in an arithmetic progression.
The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = $20500
The fee in 2018 is the 19th term of the sequence. Therefore,
T19 = $45,4120
n = 19
Therefore,
454120 = 20500 + (19 - 1) d
454120 - 20500 = 19d
18d = 433620
d = 24090
Therefore, an
equation that can be used to find the tuition y for x years after 2000 is
y = 20500 + 24090(x - 1)
Therefore, at 2020,
n = 21
y = 20500 + 24090(21 - 1)
y = 20500 + 481800
y = $502300
It would be -4,4 and -8,3
Answer:
375/15=25
Step-by-step explanation:
if the train is traveling at 375miles in 15hrs you need to divide the total miles by time traveled to get miles per hour.
3% x
100 $700
Cross multiply and divide your only number which is 100.. 3 is your percent so it has to be over 100 and your x is your variable, your unknown number over $700 Set it up like a Fraction ! 3 times 700= 2,100 divide it by 100 which is equaled to 21 So 21 is like your percent !! Hope this helped...
