Nizar buys one cake for  $2.30 and mini-bagels for $0.95 each. He spends a total of  $16.55.  Assume there is no sales tax where Nizar lives.

(BEFORE you click on your answer, write the equation in your notebook because you will need it for the next question.)

 Part A:     Which equation represents the situation?

• 2.30c + 0.95 = 16.55, where c  represents the number of cakes.

• 2.30m + 0.95 = 16.55, where  m represents the number of mini-bagels.

• 0.95m + 2.30 = 16.55, where m   represents the number of mini-bagels.

• 0.95c + 2.30 = 16.55, where  c represents the number of cakes.
