6.70-10.00=3.30
So you get $3.30 as change
A number(p) plus six
six plus a number(p)
Answer:
(Kind of cheating but since you're timed I'm just gonna five you the answer:
3/11
Step-by-step explanation:
I got this by guessing a bit, I used what varibles I had and 0.27 & 3 and used them.
So 3/0.27 = 11.11 (Repeating) so then I rounded this to a whole number,
3/11 = 0.27 (Repeating)

Let the number of students in the class be x
Let the number of pieces of gum she gave out be 3x
Equation
3x + 8 = 168 This will not work out evenly. Let's try x - 1. The reason for that is because she may not give out anything to herself.
3(x - 1) + 8 = 168 This doesn't work either.
Well we have to choose. It's a rounding problem.
3x + 8 = 168 Subtract 8 from both sides.
3x = 168 - 8 Combine
3x = 160 Divide by 3 on both sides.
x = 160 / 3
x = 53.333333333
Since that can't be, we could say there were 53 students.
3x
