7.3/2 = 18.25/?
Cross multiply
18.25*2 = 7.3*?
36.5 = 7.3*?
Divide both sides by 7.3
36.5/7.3 = ? (Because 7.3/7.3 is 1 you’re just left with ?)

The amount invested is $ 470
<h3><u>Solution:</u></h3>
Given that , we have earned $131.60 as simple interest for an amount deposit at the rate of 4% for seven years.
We have to find the amount invested. That is, we need to find the principal sum
Let us use the simple interest formula
<em><u>The simple interest is given as:</u></em>

Here, simple interest = $ 131.60
Rate of interest = 4 %
Number of years = 7
principal = ?
Substituting the values in formula, we get

Thus the amount invested is $ 470
