Question 1172573: The Instructions: Solve this word problem using an inequality. Express the answer as an inequality. Show your work.
The Problem: Gary wants to buy a computer that costs $645. He earns about $10 per hour at his new job after taxes are deducted from his paycheck. At least how many hours does he have to work before he can buy the computer?
What I did:
$10 (x) = $645
I divided $10 by $10 and cancelled it out on the left side, then I divided $645 by $10.
I got 64.5 and wasn't sure if I should round or not.
x = 64.5
Then I thought about using ≥.
$10 (x) ≥ $645
I did the same thing I did before and got
x ≥ 64.5
Then I rounded up to get this.
x ≥ 65
I'm not sure if I'm allowed to round. It didn't tell me to, but I'm not sure if it's something that's assumed, could you please help me figure this out?
