The value of x is 4
Step-by-step explanation:
The formula for simple interest is:
[tex]Simple\ interest = P *r * t[/tex]
Here
P is principal amount
r is interest rate
and t is the time in years
We know
Interest = $840
Rate = r = 5%
P = $4200
Putting the values in the formula
[tex]840 = 4200 * 0.05 * t\\840 = 210 * t\\t = \frac{840}{210}\\t = 4[/tex]
Hence,
The value of x is 4
