Katherine is purchasing flower baskets to be placed on each table at a volunteer appreciation lunch.
Store A charges $19.25 per flower basket plus a $15 delivery fee.
Store B charges $17.50 per flower basket plus a $30 delivery fee.
Which inequality can determine x, the maximum number of flower baskets that can be ordered for the total cost of store A to be less than the total cost of Store B?
19.25 + 15x > 17.5 +30x
19.25 + 15x < 17.5 +30x
19.25x + 15 > 17.5x + 30
19.25x + 15 < 17.5x + 30
Which situation can be modeled by the inequality below?
10x + 75 > 6.50x + 120

Faith rents space to sell her paintings for $450. She spends $40 to purchase materials for each painting. Faith sells her paintings for $150 each. Which inequality shows the least number of paintings she must sell in order to make a profit?
450 + 40x < 150x

450 - 150x > 40x
Which of the equations matches the model shown below?
3x + 10 = 5x + -8
-3x + 10 = 5x - 8

John wants to order school spirit shirts to sell as a fundraiser at future events. #1 Shirt Designs charges a $75 setup fee plus $12.50 per shirt. Tees and More do not have a setup fee but charge $15.75 per shirt. Which equation can determine the number of shirts, x, that need to be ordered for the total cost at each company to be the same?
12.5x + 75 = 15.75x
12.5 + 75x = 15.75
15.75x + 75 = 12.5x
15.75 + 75x = 12.5x
