• $2x+4\le30$

• $2x+4\ge30$

• $4x+2\le30$

• $4x+2\ge30$

Multiple Choice

Example 6: Eliana purchased some pencils for $0.45 each. She also purchased a ruler for $1.60. Eliana spent more than $1.75 on the ruler and pencils. Which inequality can be used to find p, the number of pencils that Eliana could have purchased?

• $0.45p+1.60<1.75$

• $0.45p-1.60>1.75$

• $0.45p+1.60>1.75$

• $0.45p-1.60<1.75$

Multiple Choice

Exit Ticket: Sue and Cathy have $20 left for a cab fare home. The cab fare is $3 per mile plus a $2 fixed charge. Which inequality shows the maximum number of miles, x, they will be able to travel in the cab?

• $2x+3\le20$

• $2x+3\ge20$

Multiple Choice

• $20x+50\ge250$

• $20x+50\le250$

• $50x+20\ge250$
