Answer 1

Answer:

Step-by-step explanation:

Given that Jared invested some money in a company's stock. Luckily for Jared, the company became very popular and the value of Jared's investment this morning is 7 times as large as the value of his investment yesterday morning.

a) Suppose Jared invested amount P

Today its value is 7P

i.e. 700% of yesterday value is value of Donald's investment this morning

b) Increase in value in one day from yesterday to today = 6 times P

i.e. increase in percent = 600%

Change in investment = +600%
