Mira bought $500 of Freerange Wireless stock in January of 1998. The value of the stock is expected to increase by 7.5% per year. Predict the year the value of Mira's stock will reach $700.

2003

Step-by-step explanation:

The main topic of the question is compound interest.

If the percentage increase is 7.5%. Then the decimal multipiler would be 1.075. The 1 in front of the decimal represents the increase. 7.5 in decimal form is 0.075, so we just add the two together to get our decimal multiplier.

Now we do trial and error to see when we reach $700. After we get at least $700, we count how many times we multiplied $500 by the decimal multiplier and onwards to figure out the number of years it took and then add that to 1998.

1) 500 x 1.075 = $537.50

2) 537.50 x 1.075 = $577.81

3) 577.81 x 1.075 = $621.15

4) 621.15 x 1.075 = $667.74

5) 667.74 x 1.075 = $717.8205

1998 + 5 = 2003

The value of Mira's stock will reach $700 in January of 2003.

I hope this helps.

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
