Text Messages

Question

Vin pays Verizon a monthly fee of $55 for his cell phone. He also pays $0.30 for each text. If his cell phone bill for October is $90.10, how many text messages did he send? 

 

 Write an equation to solve the problem

 

Answer 1

55 is a constant. The amount of text messages represent a variable we'll call x. .30 represents the coefficient next to the variable.

 

55 + .30x = 90.10
