​November 9

​

​

​

​Sue has a maximum of $120 in her account

​

​Chen's account balance is above $50

​Angelica has no more than $230 in her account

​Kadeem has at least $72 in his account

​Use key words to write an inequality for each bank account below.

Multiple Choice

Bo's account has no less than $15.

Which inequality represents this scenario?

• $$B<15$$  

• $$B\le15$$  

• $$B>15$$  

• $$B\ge15$$  

​Darts that land in white are worth 2 points. Darts that land in gray are worth 4 points.

If Kel scored no more than 40 points, write an inequality to represent the possible combinations of x, the number of darts that landed on white and y, the number of darts that landed on gray.​

Multiple Choice

If Eric scored at least 52 points, write an inequality to represent the possible combinations of x, the number or darts that landed on white and y, the number of darts that landed on gray.

(White is 2 points. Gray is 4 points.)

• $$2x\ +\ 4w\ <\ 52$$  

• $$2x\ +\ 4y\ \le\ 52$$  

• $$2x\ +\ 4y\ >\ 52$$  

• $$2x\ +\ 4y\ \ge\ 52$$  

Would it be possible for Kel to have had 15 darts that landed on white and 3 darts that landed on gray? Explain.

Multiple Choice

Would it be possible for Eric to have had 8 darts that landed on white and 10 darts that landed on gray? Explain.

$$2x\ +\ 4y\ \ge\ 52$$  

• No, Eric scored more than 52 points.

• No, Eric score less than 52 points.

• Yes, Eric scored more than 52 points.

• Yes, Eric scored less than 52 points.
