• B) E = 150(A + B - 60 \()^2\) + 155(A + B - 55 \()^2\) + 165(A + B - 70 \()^2\) + 170(A + B - 62 \()^2\)
• C) E = (150A - 60B \()^2\) + (155A - 55B \()^2\) + (165A - 70B \()^2\) + (170A - 62B \()^2\)
• D) E = (150A + B - 60 \()^2\) + (155A + B - 55 \()^2\) + (165A + B - 70 \()^2\) + (170A + B - 62 \()^2\)
