Question

Tim's phone service charges $26.60 plus an additional $0.25 for each text message sent per month. if tim's phone bill was $32.85, which equation could be used to find how many text messages, x, tim sent last month?

Answer 1

$26.60 + $0.25t= $32.85

To Solve:
$26.60 + $0.25t= $32.85
$26.60 - $26.60+ $0.25t= $32.85 - $26.60
$0.25t  = $6.25
$0.25t/$0.25 = $6.25/ $0.25
t= 25
