Answer:
x = 48/7
Step-by-step explanation:
There's two good ways to do this problem.
Option 1:
Translate "x varies directly as y" into the equation y=kx
Then you have to find k. After you "reset" your y=kx equation, fill in k and then solve for x. See image.
Option 2:
Translate "varies directly" into a proportion, which is two fractions equal to each other:
x/y = x/y
Fill in the three numbers given and cross multiply and solve to find the fourth number. See image.

Step-by-step explanation:
Given,
Purchased amount of the bond, P = 3500,
Annual rate of simple interest, r = 4.89% = 0.0489,
Time ( in years ), t = 3,
Since, the total amount of a bond that earns simple interest is,
By substituting values,
The amount of the bond would be,
