Find compound amount annually of p=4000,time=3/2 and rate =10% solve it step wise.

Natalka [10]

Step-by-step explanation:

Hey, there!!

Principal (p) = 4000

Time = 3/2= 1.5 yrs.

rate = 10%

Now, we have formula,

$c.a = p \times {(1 + \frac{r}{100}) }^{t}$

Putting their values,

$ca = 4000\times {(1 + \frac{10}{100} )}^{1.5}$

$ca =4000 \times {(1 + 0.1)}^{1.5}$

$ca = 4000 \times 1.153689$

Simplifying them we get,

C.A = 4614.75

Hope it helps...
