Question

For his long distance phone service, Juan pays an $8 monthly fee plus 6 cents per minute. Last month, juan's long distance bill was $16.58. For how many minutes was Juan billed ?

Answer 1

your equation is 0.06m+8=c

m=minute(s)
c=overall cost

16.58 - 8.00 = 8.58
8.58/.06=143
so Juan was billed for 143 minutes :D
