Question

Chelsea earns 30 per day plus 5 for every sale that she makes at her job In Thursday she want to earn at least 60

Answer 1

The equation of her earning is: 30 + 5x
Where, x = number of sale

Now, 30 + 5x = 60
5x = 60-30
x = 30/5
x = 6

So, If she wants to earn 60, she need to work for 6 sales

Hope this helps!
