Solve the problem.Janet is planning to visit Arizona, New Mexico, and California on a 16-day vacation. If she plans to spend as much time in New Mexico as she does in the other two states combined, how can she allot her time in the three states? (Let x denote the number of days in Arizona, y the number of days in New Mexico, and z the number of days in California. Let z be the parameter.)
A. x = 8 - z, y = 8, 0 ? z ? 8 B. x = 8, y = 8 - z, 0 ? z ? 8 C. x = 8, y = z - 8, 0 ? z ? 8 D. x = z - 8, y = 8, 0 ? z ? 8
