Description

Sally traveled to Rochester, Des Moines and Omaha to video tape events. She paid $180, $230 & $160 per night for lodging in Rochester, Des Moines & Omaha, & her hotel bills totaled $2660. She spent $110, $120 & $90 per day for her meals in Rochester, Des Moines and Omaha, & her total expenses for meals totaled $1520. If she spent as many days in Rochester as she did in Des Moines & Omaha combined, how many days did she stay in each city?

Explanation & Answer

Thank you for the opportunity to help you with your question!

the # of day in 3 cities are R D O respectively, then we have

180R+230D+160O = 2660

110R+120D+90O = 1520

R = D+O

Solve this equation, we have

R=7, D=4, O=3

Please let me know if you need any clarification. I'm always happy to answer your questions.
