Hello, Judi!
I had to baby-talk my way through this one . . .
Sixty cookies were to be equally distributed to campers.
When 8 campers did not want the cookies, the other campers each received 2 more cookies.
Which of the following equations could be used to find the number of campers ?
With campers, each got cookies each.
With campers, each got cookies each.
Since the number of cookies was 60: .
Multiply: .
Simplify: .
Multiply by
Divide by . . . answer choice (a)
~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
I just noticed . . .
The discriminant for equation (b) is: . . . negative!
. . So equation (b) has no real roots.
So the answer is . . . "by elimination"?
