Question

For his long distance phone service, Goran pays a $6 monthly fee plus 8 cents per minute. Last month, Goran's long distance bill was 20.64$. For how many minutes was Goran billed?

Answer 1

x = # of minutes

$6 + $0.08x = $20.64. Subtract 6 from both sides

$0.08x = $14.64. Divide each side by $0.08

x = 183

Goran was billed for 183 minutes
