Answer:
$36 400
Step-by-step explanation:
Step 1
The first step is to figure out how much money is saved at the end of each month for the period from January 1 to June 15. The amount deposited at the end of each month is obtained by multiplying the amount from the previous month by 3.
The amount deposited in January is [tex]\$100.[/tex]
The amount deposited in February is [tex]1\$00\times 3= \$300.[/tex]
The amount deposited in March is [tex]\$300\times 3= \$900.[/tex]
The amount deposited in April is [tex]\$900\times 3= \$2\700.[/tex]
The amount deposited in May is [tex]\$2\,700\times 3= \$8\,100.[/tex]
The amount deposited in June is [tex]\$8\,100\times 3= \$24\,300.[/tex]
Step 2
The next step is to add up all the money that was deposited into the account. This calculation is shown below,
[tex]\$100+\$300+900+\$\$2\,700+\$8\,100+\$24\,000=\$36\,400[/tex]
