Answer:

Examining the total amount of money put into the accounts, and the results in

the tables on the following page, we make the following observations.

Monique’s parents’ put $100 into her account every year for 6 years, which is a

total of $100 × 6 = $600. At the end of 15 years, she had $2000 in her account,

which means her account earned a total of $2000 − $600 = $1400 in interest over

15 years.

Tyrel’s parents put $100 into his account every year for 10 years, which is a total

of $100 × 10 = $1000. At the end of 15 years, he had $1752 in his account, which

means his account earned a total of $1752 − $1000 = $752 in interest over 10

years.

Clearly, Monique’s parents had the better savings strategy. Even though her

parents put only $600 into her account in the first 6 years, her account earned

significantly more interest because the money was in the account for a longer

period of time.
