So Jeremy had x amount of money to begin with
he then spent $17 and was left with $75 to spend for camp so
x-17=75
add 17 to both sides
x=92
congrats, you're doing algebra
Rearrange to: x^2 + 18x - 25 = 0
Then factorise (I like to do it by completing the square):
(x + 9)^2 -81 -25 = 0
(x + 9)^2 = 106
x + 9 = sqrt(106)
The sol'ns are:
x = -9 + and - sqrt(106)
Answer:
I think its 2 kg anyone correct me if I'm wrong!
All you would do is divide 9.99/15 to get how much one pound costs.
The answer would be around 66 or 67 cents.
9.99/15=.666
