Anand is a plumber hoping to make at least $250 on his next job. If he charges an initial fee of $65 and an hourly rate of $28. Create an inequality to model the minimum number of hours of work (h) Anand should work.

• 28h + 65 = 250

• 65h + 28 ≥ 250

• 28h + 65 ≥ 250

• 28h + 65 > 250

Anand is a plumber hoping to make at least $250 on his next job. If he charges an initial fee of $65 and an hourly rate of $28, what is the minimum number of hours of work (h) Anand should work?

Note: Anand charges one full hour at a time.

• He should work at least 6 hours.

• He should work 6.6 hours.

• He should work at least 7 hours.

• He should work at most 6 hours.

You have a phone card worth $20. There is a $1.10 charge to activate the card. It is $0.42 minutes per minute to talk on the phone. Create an inequality to model using the phone card.

• 1.10x + 0.42 ≤ 20

• 0.42x + 1.10 ≤ 20

• 0.42(20) + 1.10 ≤ x

• 0.42x + 1.10 = 20
