7-36.

When Lorretta was $18$ years old, she deposited $100$ into a $20$-year certificate of deposit (CD) account that earns interest at a better rate than her standard savings account. She must leave the money in the account for $20$ years, without making any withdrawals or deposits. Six years later, she had $132$ in the account. Write an equation that will represent this situation, and use the equation to determine how much money Lorretta will have in her CD after $20$ years. Homework Help ✎

$100\left(x\right)^{6} = 132$

$y = 100(1.047)^x$
