Answer:
Step-by-step explanation:
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
![5*x+30>50\\5x>50-30\\5x>20](https://tex.z-dn.net/?f=5%2Ax%2B30%3E50%5C%5C5x%3E50-30%5C%5C5x%3E20)
Dividing both sides by 5
![\frac{5x}{5}>\frac{20}{5}\\x>4](https://tex.z-dn.net/?f=%5Cfrac%7B5x%7D%7B5%7D%3E%5Cfrac%7B20%7D%7B5%7D%5C%5Cx%3E4)
