The millers plan on retiring soon. when they were first married they purchased 1,000 shares in a mutual fund that was at that time paying $10 a share. now, thirty years later it is paying $78 a share. what is the percent increase for the fund?

There is 680% increase for the fund.

Step-by-step explanation:

Since we have given that

Number of shares they purchased = 1000

Cost of per share at the time of their marriage = $10

So, Amount of fund will be

Cost per share after 30 years = $78

So, Amount of fund will be

Percentage of increase for the fund will be given as

Hence, there is 680% increase for the fund.

yes. we do proportions in probabilities.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
