Find 12a + 2b - 4, where a = 3 and b = 5

—42– because if you multiply 3 by 12 you get 36, just like if you multiply 2 by 5 then you get 10. Add those two together and you get 46 then you must subtract 4

Ithink you're supposed to multiply 12.50 which is how much he makes per hour and then multiply it by each number then add whats left togrther and there's your answer
