Oh sorry...forgot I had this opened in another tab....

Okay well we know that the amount decreased already is more than 150 dollars over the past 5 days...

so we know it must be a greater than sign...because if it was exactly 150 it would be greater than or equal to!...so

$$5x > 150$$

so we know that if we divide both sides of the equation by 5 we get

$$x > 30$$
