Answer:

Step-by-step explanation:
Given : Jill has a job offer. She is offered either $50 per day or ?30 per day plus a commission of $3 for every plant she sells.
To Find: How many plants does she need to sell to make the commission offer the best paying option?
Solution :
Since in the commission offer
She earns $ 30 per day and $3 for each plant she sells
Let she sold t plants
Since commission of 1 plant is $3
So, commission of t plants is $3t
And She is also getting $30 per day
So, total amount earned in the commission offer is 30+3t
Since we need to find How many plants does she need to sell to make the commission offer the best paying option
So, 30+3t > 50
⇒![3t > 50-30](https://tex.z-dn.net/?f=3t%20%3E%2050-30)
⇒![3t > 20](https://tex.z-dn.net/?f=3t%20%3E%2020)
⇒![t > \frac{20}{3}](https://tex.z-dn.net/?f=t%20%3E%20%5Cfrac%7B20%7D%7B3%7D)
⇒![t >6.6](https://tex.z-dn.net/?f=t%20%3E6.6)
Thus she must sell 7 or more plants
Hence she need to sell 7 or more plants to make the commission offer the best paying option
