• x<-21
• x<21

Yellow Cab Taxi charges a $1.75 per passenger, x, in addition to $0.65 per mile, y. Katie has no more than $10 to spend on the taxi ride.

• 1.75x + 0.65y < 10

• 1.75x + 0.65y > 10

• 1.75x + 0.65y < 10

• 1.75x + 0.65y>10

Match the inequality to the word problem.Katie wants to have at least $200 in her bank account by the end of the month. She makes $25 for each dog that she walks and $12 for each cat that she feeds. How many dogs, x, and cats, y, would she have to take care of to make at least $200.

• 25x - 12y ≥ 200

• 25x + 12y ≥ 200

• 12x + 25y ≥ 200

• 25 x+ 12y > 200

A limo driver needs to make more than $4500. He charges a rental fee of $375 per day and $0.85 per mile. What inequality represents the number of days, x, and miles, y, he would have to drive to make more than $4500.

• 0.85x + 375y > 4500

• 375x + .85y < 4500

• 375x + .85y > 4500

• 0.85x + 375y < 4500

• 5.50x + 7y < 5225

• 5.50x + 7y ≥ 5225

• 7x + 5.50y ≥ 5225

• 5.50x + 7y ≤ 5225

• 15.99x + 9.99y ≤ 100

• 15.99x + 9.99y > 100

• 9.99x + 15.99y ≤ 100
