The average age of the seven apprentice magicians is 143 years. The average age of the seven apprentice magicians and the head wizard is 150 years. How old is the head wizard in years? Please need answer ASAP!!!!!!!!
assume each of the original three magicians is 143 years old 143 x 3 = 429 150 x 4 = 600 this means that the ages of the original three (429) plus the age of the head magician is 600 600 - 429 = 171
it would be 200 points. Lets assume that all of the apprentice magicians are 143 years old. If so, then 143 x 7 = 1001. 1001 + 200 = 1201. 1021 ÷ 8 (the number of magicians) the answer is 150. so the age of head wizard is actually 200 years.
