Answer: 2.16
Step-by-step explanation:
Cost at B = Cost at A * (Cost index of B / Cost index of A)
Cost at A = $1,050,000 Rapid City
Cost at B = $2,500,000 Andros Island
Cost index at A = ACF of 0.91
Cost index at B = ?
2,500,000 = 1,050,000 * (Andros ACF / 0.91)
2,500,000 * 0.91 = 1,050,000 * Andros ACF
Andros ACF = (2,500,000 * 0.91) / 1,050,000
Andros ACF = 2.16
