Answer:
The amount into account after a year is $1042
Step-by-step explanation:
Given as :
The principal amount into the account = p = $1000
The amount is growing at the rate = r = 4.2 % per year
Let The Amount into account after 1 year = $A
So, According to question
The amount into account after 1 year = The principal amount × [tex](1+\dfrac{\textrm rate}{100})^{\textrm time}[/tex]
Or, A = p × [tex](1+\dfrac{\textrm r}{100})^{\textrm 1}[/tex]
Or, A = $1000 × [tex](1+\dfrac{\textrm 4.2}{100})^{\textrm 1}[/tex]
Or, A = $1000 × 1.042
Or, A = $1042
So, The amount into account after a year = A = $1042
Hence,The amount into account after a year is $1042 . Answer
