Answer:
The amount is $1480.24
Step-by-step explanation:
We are given
he puts $1000 in a savings account earning 4% annually after 10 years
so,
P=1000
r=4%=0.04
t=10
now, we can use formula
[tex]A=P(1+r)^t[/tex]
now, we can plug values
[tex]A=1000(1+0.04)^{10}[/tex]
[tex]A=1480.24428[/tex]
So,
The amount is $1480.24
Answer: a. $1428.24
Step-by-step explanation:
Given formula : [tex]A=P(1+r)^t[/tex] , where P is initial amount inveted , r is rate of interest ( in decimal) and A is the compound amount at the end of t years.
If Mario puts $1000 in a savings account earning 4%(4% = 0.04 in decimal ) annually after 10 years, then substitute P=1000 ; r= 0.04 and t=10 in the given formula , we get
[tex]A=1000(1+0.04)^{10}=1000(1.04)^{10}=1480.24428492\approx1480.24[/tex]
Hence, the amount he will get after 10 years = $1428.24
