@Lalit Mandal that is an excellent educated guess! The reason I say it's a guess: dollars don't have an integer constraint. We weren't told that Makoto earned an integer $ hourly rate. For example, if the total amount paid was $507, the correct answer would be B. (and Makoto would have earned $7.80 per hour).
@@QuantReasoning Hey Avi..!! Now this is unfair of you to change the question parameters and eventually answer 😊 I did so within the realms of that question. However, point accepted.
I got the hourly rate which was quick 780/65 = 13 then I multiplied by 15 M’s hours =180
Divide using approximation
Also, Makoto's payment must have factors 3 and 5. Only D is possible.
