Final answer:

The value of Enrique's investment this morning is 700% of the value of his investment yesterday morning. The value of Enrique's investment changed by 600% from yesterday morning to this morning.

Step-by-step explanation:

To find the value of Enrique's investment this morning as a percent of the value yesterday morning, we can set up the equation:

x = 7y

where x represents the value of the investment this morning and y represents the value of the investment yesterday morning. We can solve for x as a percentage of y by dividing x by y and multiplying by 100:

(x/y) * 100 = (7y/y) * 100 = 700%

Therefore, the value of Enrique's investment this morning is 700% of the value of his investment yesterday morning.

To calculate the percent change in the value of Enrique's investment from yesterday morning to this morning, we can use the formula:

Percent Change = ((New Value - Original Value) / Original Value) * 100%

In this case, the original value is y and the new value is x. Plugging in the values, we get:

((x - y) / y) * 100 = ((7y - y) / y) * 100 = 600%

Therefore, the value of Enrique's investment changed by 600% from yesterday morning to this morning.
