Answer:
90050+10x; At least 85 hours
Step-by-step explanation:
Nick must make at least 900 dollars, so the amount he has + earns must be greater than or equal to 900 in order to walk out of the store with it.
50 is the amount that Nick already has, and add that to 10x, which gives $10 for every x hour.
To solve, subtract 50 from each side.
85010x
Divide by 10 to solve for x:
85x
Nick must work at least 85 hours.
