The Millers plan on retiring soon. When they were first married they purchased 1,000 shares in a mutual fund that was at that ti

kozerog [31]

Answer: 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

$1000\times 10=\$10000$

Cost per share after 30 years = $78

So, Amount of fund will be

$78\times 1000=\$78000$

Percentage of increase for the fund will be given as

$\frac{78000-10000}{10000}\times 100=680\%$

Hence, there is 680% increase for the fund.
