Answer :
Mia will need to invest A. $1,600,000 to get a yearly income of $40,000.
Step-by-step explanation:
Step 1; Mia finds a CD which has a 2.5% interest over a year. So Mia will get back 2.5% of the amount invested into the CD. So we need to calculate how much 2.5% of 1,600,000, $1,800,000, $1,500,000 and $1,200,000 are. To do this we convert 2.5% into a fraction and multiply it with the value.
Step 2;
2.5% of $1,600,000 = [tex]\frac{2.5}{100}[/tex] × $1,600,000 = $40,000.
2.5% of $1,800,000 = [tex]\frac{2.5}{100}[/tex] × $1,800,000 = $45,000.
2.5% of $1,500,000 = [tex]\frac{2.5}{100}[/tex] × $1,500,000 = $37,500.
2.5% of $1,200,000 = [tex]\frac{2.5}{100}[/tex] × $1,200,000 = $30,000.
So she will have to invest A. $1,600,000 to get a yearly income of $40,000 when she retires.
