Answer» The key here is to first determine the cost of 1 child for 1 week.Set x= cost of one childw= number of weeksw*x = 18008(50)x = 1800400x = 1800Divide each side by 400x = 1800/400 = 4.5So 1 child per week = 4.5To solve for number of weeks Rs.21060 pays for,Set y = number of weeksy*4.5 = 21060Divide each side by 4.5y = 21060/4.5 = 4680 |
