DIRECTIONS: Use this information to answer Parts A and B. The number of students enrolled at a college is modeled by S(t)=40t+2000, and the average tuition paid per student, in thousands of dollars, is modeled by T(t)=0.05t2+0.7t+15. In both models, t represents the number of years since 2010.
Question 1
Part A
Write function R(t) to model the annual revenue that the college receives from tuition payments.
Enter the correct polynomial in standard form in the box.
R(t)=

Part B
Predict the revenue received in 2020.
Enter the correct value in the box.

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
