Question

a karate studio charges $35 for the first course and $22.50 for each course after that, even if the student leaves the course early. cena paid $170 for her son to take courses. how many courses did he take? 6 courses 7 courses 8 courses 10 courses

Explanation:

Step1: Subtract first course cost

Total paid is $170, first course is $35. So remaining for other courses: $170 - $35 = $135.

Step2: Find number of additional courses

Each additional course is $22.50. So number of additional courses: $135 / $22.50 = 6.

Step3: Total courses

Add first course: 6 + 1 = 7.

Answer:

7 courses
