Julie is a math tutor. She charges each student $210 for the first 7 hours of tutoring and $20 for each additional hour. When the number of hours (h) that Julie spends tutoring a student is greater than 7 (h > 7), the equation that gives the amount (A) that Julie earns in dollars is A = 210 + 20(h + 7) A = 210 + 20(h - 7) A = -210 + 20(h - 7) A = 210 + (h - 7)/20. If Julie earns $410 tutoring one student, solve for the total number of hours she spent tutoring the student.
