January: 110 - 135 = -$25
February: 85 - 110 = -$25

April: 130 - 95 = $35
May: 145 - 100 = $45
June: 165 - 105 = $60
Answer:
you have to use the Pythagorean theorem. a^2 + b^2= c^2
72^2 + b^2 = 75^2
5184 + b^2 = 5625 (subtract 5184 from both sides)
b^2= 441 (find the square root of each side)
b= 21
