Test 1 - Solving Equations & Inequalities Review

Mr. Roast buys 2 lb of turkey and 12 lb of ham. The total cost is $30. The ham costs $2 per lb.

Create an equation to find the cost of 1 lb of turkey.

• 2y + 12x = Romero

• 2x + 12(2) = 30

• 30 + 2x = 12(2)

• 12(2) = 2x

Lisa went to the mall to do her back-to-school shopping.  When she returned, she noticed that the number of shirts (s) she purchased was 3 more than twice the number of pants (p) she bought.  What is an equation that can be used to represent the number of shirts Lisa purchased? 

• p=3 + 2s
• s + 2p =3
• s = 3 + 2p
• 2p = s + 3

The Roaming Cell Phone Company charges $15.00 per month plus $0.20 per minute of airtime usage.  If Juanita's monthly bill was $56.20, what is an equation that can be used to determine her total minutes (x)?

• 56.20 = 15 + 0.20x
• 56.20 =15 (0.20x)
• 56.20 = 15 + x + 0.20
• 56.20 = 0.20 + 15x
