Answer 1

$\text{We need to find how many minutes Scott had in his phone service}\\\\\text{We know that he pays \ 6 a month, 0.08 cents per minute, and was}\\\text{billed \ 17.92 in total}\\\text{Turn this into an equation:}\\\\17.92 =0.08x+6\\\\\text{Solve for x:}\\\\17.92 =0.08x+6\\\\\text{Subtract 6 from both sides}\\\\11.92=0.08x\\\\\text{Divide by 0.08}\\\\x = 149\\\\\boxed{\text{Scott was billed for 149 minutes}}$
