Answer: There are approximately 13 lessons that Jeanie take.
Step-by-step explanation:
Since we have given that
Registration fees = $50
Cost of each lesson = $35
Total amount he spend = $500
Let number of lessons be 'x'.
So, our equation becomes,
[tex]50+35x=500\\\\35x=500-50\\\\35x=450\\\\x=\dfrac{450}{35}\\\\x=12.85\\\\x\approx 13[/tex]
Hence, there are approximately 13 lessons that Jeanie take.
