# Lydia pulled into a rest stop in St. Louis, MO, to take a look at her road atlas.

Lydia pulled into a rest stop in St. Louis, MO, to take a look at her road atlas. She's driving from Chicago, IL, to Memphis, TN, to visit an old friend from college, and wants to know how many miles her trip will be. She knows that she already traveled 300 miles to get to St. Louis, and will average about 60 miles per hour once she leaves for Memphis.

total number of miles (M) Lydia will drive, where H represents the number of hours it takes to drive from St. Louis to Memphis?

1. 300H+60=M
2. 60H+300=M
3. 300M+60=H
4. 60M+300=H

Mimi can usually pack all of her groceries into a few bags so that she can manage the bus ride home without much trouble. On her latest trip, she had too many heavy items and decided to call for a cab. She had a few ride apps on her phone, and used them to compare the prices of two companies: Golden Taxi and Fab Cab.

Golden Taxi charged an initial fare of \$3, plus an additional \$0.50 per mile. Fab Cab charged an initial fare of \$2, but each mile costs an additional \$0.80. Mimi had only a \$10 bill to pay for her ride.
