Answer: $11,000
Explanation:
Hi, to answer this question we have to write an equation: 
The total savings that Jenna has ( x) multiplied by the percentage of her savings that are in bonds, in decimal form (20/100), must be equal to the amount of savings in bonds (2,200) 
Mathematically speaking: 
x (20/100) =2200 
Solving for x: 
x (0.2)= 2,200 
x = 2,200/ 0.2 
x = $11,000
