To effectively and correctly answer this and help we'll need a photo diagram for the question. We need to see a graph of some sort to even know where to start this off. It'd probably be solvable without a diagram if you don't have one, but I don't think that many people have the skill to do so (at least I don't). I know how terrible I feel when no one answers my questions, so I thought I'd let you know why others might not be answering this for you. I'm pretty sure you can update the question and attach a photo (an actual photo or a screenshot) to it, via the paperclip icon. Have a great day! :)
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
How many times does 18 go into 7? The answer is 2 times since 14/7 = 2 and we'll have 4 left over. We can say that 18/7 = 2 remainder 4. The remainder of 4 is placed over the denominator 7 to indicate we a fractional part.
Therefore, 18/7 = 2 & 4/7
