If each of the 28 students made at least $25, you would multiply 28 and 25 together to obtain the least amount of money the class raised. That gets, 28x25 = 700. The class made at least $700.

Answer:
I believe he can go on 30 rides.
Step-by-step explanation:
The equation would be 5 + .5x = 20
Because $5 to get in, plus $.50 per ride (x is number of rides you are solving for), and $20 is total amount you can spend.
So, .5x=15 so x=30
Answer:
8, 10, 3
Step-by-step explanation:
For finding real solutions to cubic equations and those of higher degree, I find a graphing calculator to be useful. The problem can be cast in the form ...
f(x) = 0
where f(x) is the difference between the product of the integers and 240:
f(x) = x(x +2)(x -5) -240
Then all we need to do is ask the calculator to show the x-intercept. It is x=8.
So, the three integers are ...
Answer:
Option 2: 27 is the correct answer.
Step-by-step explanation:
Given functions are:

As we can see that the function g(x) in written in terms of f(x), first of all we have to find g(x) by putting the value of f(x) in g(x)
So putting f(x) = x^2-2 in g(x)

As g(-3) has to be found, putting x=-3 in g(x)

Hence
Option 2: 27 is the correct answer.
