Question

jennifer grabdma brought her a $50 savings bond when she was born. When jennifer is 30 years old, the bond will have earned 110% in interest.How much will the bond be worth when jennifer is 30 years old?

Answer 1

In this problem 50 is the initial price and the 100% so we can use a rule of 3 to find the 110%

`\begin{gathered} 50\to100 \\ x\to110 \end{gathered}`

So the equation is:

`x=(50\cdot110)/(100)=55`

So at the end she will have:

`50+55=105.00`

So is option b
