Alright.. so the operations would be multiplication and addition.
The reason for this is you're finding the amount the school got --24*8-- and the amount the homeroom got --24*3-- then add those to get the total he got.
Let's use the variable 't' to represent the total he collected.
We know that the school gets 8 for every book and he sold 24, so this can be represented with 8*24.
We also know that the homeroom gets 3 for every book, so 3*24. Both of these added will give you the total amount of money he earned, 't'.
So the sentence can be written as
t=8(24)+3(24).
t=192+72.
t=264.
So, we can see that the total he earned was $264.
If you look back at the equation, we know that the 8*24 represents the amount the school earned, which means that school earned $192.
The same goes with the amount the homeroom earned; we know that this is represented by 3*24, and thus the homeroom earned $72.
And that's it!!! (:

Answer:
There are two roots:
(3 + √69)/2 and (3 - √69)/2
Step-by-step explanation:
Use the quadratic equation to solve this...
x = [-b ± √(b² - 4ac)]/(2a)
Here, a = 1, b = -3, and c = -15, plug them in and simplify
x =([-(-3) ± √[(-3)² - 4(1)(-15)])/[2(1)]
x = (3 ± √[9 - (-60)])/2
x = (3 ± √69)/2
so
x = (3 + √69)/2 and x = (3 - √69)/2
