Bob invested his savings in two investment funds. The amount he invested in Fund A was $4000 less than the amount he invested in Fund B. Fund A returned a 7% profit and Fund B returned a 3% profit. How much did he invest in Fund B, if the total
profit from the two funds together was $1520?

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.

9 x 8 divided by (5-3)=36
