Hey there!
Consider the exponential growth equation:
, where:
P = initial amount
r = interest rate (as a decimal, divide a percentage by 100 to get its decimal form)
t = years
All you need to do is plug in your given numbers:
P = 120
r = 0.10
t = x
Your final equation will be:
Hope this helped you out! :-)

ANSWER
B. x=3,y=2
EXPLANATION
The given equations are
and
We add the two equations to eliminate y.
This implies that that:
Simplify:
Divide both sides by 2.
We put x=3 into any of the equations to find y.
Let us substitute x=3 into equation (1) to get:
Divide both sides by -3 to get;
The solution is therefore x=,y=2.
