Answer:x=2; second option
Step-by-step explanation:
120+10x=140
10x=20
X=2
The formula of the future value of annuity ordinary
Fv=pmt [(1+r)^(n)-1)÷r]
Fv future value
Pmt payment per year 4000
R interest rate 0.0215
N time 5 years
Fv=4,000×(((1+0.0215)^(5)−1)÷(0.0215))
fv=20,878.69
Answer:
5,3
Step-by-step explanation:
Simplify both sides of the equation
Isolate the variable
