Answer:

A. 592 - 286 - 49 = c

Step-by-step explanation:

A school sold brownies and cupcakes at a bake sale. There were 592 total items available for sale. All 286 brownies were sold. Of the cupcakes for sale, 49 did not sell. How many cupcakes did sell at the bake sale?

The cupcakes that sold = 306 - 49

= 257 cupcakes were sold.

Therefore, the correct equation to solve. A. 592 - 286 - 49 = c
