Brenda has to take out the trash more than 4 times to have more than $50.
Step-by-step explanation:
Given,
Amount Brenda already have = $30
Amount she gets each time for throwing trash = $5
Amount she wants to have = More than $50
Let,
x be the number of times she throws trash.
Amount for throwing trash * Number of times trash thrown + Amount already have > Amount she wants to have

Dividing both sides by 5

Brenda has to take out the trash more than 4 times to have more than $50.

-> inversed= 100/78=1.28=cot x
so it is the second option
