Fifty-five and one-half percent of the shareholders in a fast food chain are under the age of 40 if the corporation is owned by 86,000 investors how many of the shareholders are 40 and over

38,270

Step-by-step explanation:

1. find the % of investors over age 40: 100-55.5% = 44.5%

2. multipliy the total number of investors by the % over age 40:

    86,000 X 44.5% = 38,270

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
