PLEASE HELP
John and Savannah are saving money to go on a trip to Mexico. They need at least $2,545 in order to go. John tutors English and Savanah works as a babysitter to raise money. John charges $15 per hour and Savannah charges $20 per hour. The number of hours that Savannah has scheduled is no more than five times the number of hours John has scheduled. Savannah will babysit at least 40 hours..

Write a set of constraints to model the problem, with x representing the number of hours John tutors and y representing the number of hours Savannah babysits.
