Let's turn that ratio into a fraction: 14/21

14/21... Let's pull some common factors out.

If I remember my times tables, 7 fits into both 14 and 21 so let's divide the top and bottom by 7:
2/3

And 2/3 is the same as 2:3

Nick has $50. He just got a job as a construction worker making $10 an hour. He wants to earn enough money to buy himself a new
Ilia_Sergeevich [38]

Answer:

900\geq50+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.

850\geq10x

Divide by 10 to solve for x:

85\geqx

Nick must work at least 85 hours.
