Answer:
k= -5
Step-by-step explanation:
When x=1 and y= -2,
x-2y+k=0
1 -2(-2)+ k=0
1+4+k=0
5+k=0
k= -5
To find the money you make, take:
x(1 (+ or -) % interest rate) * Time
So in this case, it would be:
3800(1+0.04)(1) = Ans
and
3800(1+0.07)(1) = Ans
Assumably, combining those totals would give you $218. If you take the total of 3800(1+0.04)(1), subtract that from $218.
218 - (3800(1+0.04)(1)) = Your Answer

The tip would be $15. This is because $125 by 1+tip percent, so in this case $125x1.12 which gives you 140, subtract the original amount and you have your tip! :))
