Answer:
New avaerage if 2 students (15 year old) left = 13
Step-by-step explanation:
Given:
Average age of 20 students = 13.2
Find:
New avaerage if 2 students (15 year old) left
Computtaion:
Sum of all 20 student's age = 20 x 13.2
Sum of all 20 student's age = 264
Sum of current 18 student's age = 264 - 15 - 15
Sum of current 18 student's age = 234
New avaerage if 2 students (15 year old) left = 234 / 18
New avaerage if 2 students (15 year old) left = 13
Divide the total number of yards (5 yards) by the bracelet size (18").
STEP 1:
convert total yards to inches
1 yard= 36 inches

STEP 2:
divide total inches by bracelet size
= 180 ÷ 18 inch bracelet
= 10 bracelets
