SAT - Math - Ratio and Proportion
Question 6 of SAT Math D113 has wrong options. Where do I report this?
The amount of money a teacher earns is directly proportional to the number of students he teaches. The teacher earns $ 250 when he teaches 4 students. How much will he earn if he teaches 15 students?
earning ex no of students
⇨ earning = constant × no. of students
⇨ 250 = constant × 4
⇨ Constant = = 75
So, for 15 students earning = 75 × 15 = $ 1125
For this solution, the teacher should earn $300 and not $250.
