Step-by-step explanation:
3 ax + 4ax = 5ax + 4, combine like terms
7ax = 5ax + 4, minus 5ax from both sides
2ax = 4, divide 2a on both sides
you'll be left with x = 2/a
Hi there
The formula of compounded continuously is
A=pe^rt
A future value?
P present value 300
R interest rate 0.07
T time 4 years
E constant
So
A=300×e^(0.07×4)
A=396.9 round your answer to get
A=397
Good luck!
The answer to your question is 3 1/2
