The vaulue is decreasing since you multiple by a decimal which isn’t a whole number.

Russell Schwartz · Answer 2

The value in this case would be going up. Since. 75 being multiplied by an increasing number would only increase, the value must be doing the same.

However, if that t were an exponent, the value would be decreasing. The more a number between 0 and 1 is multiplied by itself, the smaller it gets.
