After the 15% discount, Maria pays 85% of the cost. That cost is the sum of the fixed cost and the variable (per visit) cost.
... (updated cost) = 0.85×($150 +$30×a)
... (updated cost) = 127.50 +25.50a . . . . in dollars
Based on the answer choices, we suspect you intend
.. (x -1) +26 = -4x
This simplifies to
.. x +25 = -4x
.. 25 = -5x . . . . . subtract x
.. -5 = x . . . . . . . divide by the coefficient of x
Selection D appears to be appropriate for the question we think you asked.
Multiples of ten are: 10, 20, 30, 40, 50, 60, & 70.
