Answer:
2 1/2 hours, or 2 and a half hours
Step-by-step explanation:
so initial fee is 38, and then we pay an additional 12 dollars every 1/4 hour, so every hour, we need to pay him and additional 48 dollars, because 12 x 4 is 48. in an equation this is 38(amount we first pay)+48x(where x is total number of hours you went)=158(the total we payed)
38+48x=158
48x=120
x=120/48
x=30/12
x=5/2, so we payed him the equivalence of 2 and a half hours
