Answer
$142.55
Explanation
From the question, the following were given:
Principal, P = $75
Rate, R = 1.8% = 1.8/100 = 0.018/12 = 0.0015
Time, nt = 3 years x 12 months = 36 months
The amount, A in the account after 3 years can be calculated as follow
[tex]\begin{gathered} \text{A }=P(1+R)^{nt} \\ A=75(1+0.018)^{36} \\ A=75(1.018)^{36} \\ A=75\times1.900728156 \\ A=142.55 \end{gathered}[/tex]
Therefore, the amount in the account after 3 years is $142.55
