Question

Randy worked 18 hours each week for four weeks. for each of the next four weeks, he worked 1/3 fewer hours as the previous four weeks. what was the total number of hours he worked for the eight weeks

Answer 1

from 1st week to 4th: 18 x 4= 72 hours
from 5th week to 8th week: 18 x 1/3 x 4 = 48 hours
72 + 48 = 120 hours
