30h+45 is the equation u would use 30(3) +45 90+45 $135 I hope this pleases u

So since he charges $45 for the FIRST hour and there is four hours he only charges $45 for that first hour. And the rest of the time he charges $30 and he has three hours left it would be 30×3 then add the $45 from the first hour 30×3+45= 135 $135 in total
