​Matilda needs at least $112 to buy a new dress. She has already saved $40. She earns $9 an hour while babysitting.

​​In the problem above, what are the important pieces of information in order to create an inequality? Write them on a blank piece of paper.

Multiple Choice

Matilda needs at least $112 to buy a new dress. She has already saved $40. She earns $9 an hour babysitting. Select the inequality below that matches the problem.

• $$40x-9<112$$  

• $$40+9x=112$$  

• $$40\ +\ 9x\ \ge112$$  

• $$112+9x<40$$

On a separate piece of paper, write down the important pieces of information from this problem.

Multiple Choice

Ayzsa needs to get at least 159 total points to get an A in the class. If she has 47 right now and there are 4 more total assignments, how many points does she need on average to get an A? Select the inequality that represents the problem.

• $$47+4x\ge159$$  

• $$4x\ge159$$  

• $$159-4x<47$$  

• $$47x+159<4$$
