Brenda has $30. She gets $5 every time she takes out the trash. Which inequality can be used to find x, the number of times Bren
kobusy [5.1K]

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

Dividing both sides by 5

\frac{5x}{5}>\frac{20}{5}\\x>4

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