Your family goes to a restaurant for dinner. There are 6 people in your family. Some order the chicken dinner for $14.80, and some order steak for $17. If the total bill was $91, which system best represents the situation? Let "c" represent the # of people who ordered chicken and "s" represent those who ordered steak.

c + s = 6
14.80c + 17s = 91

c + s = 91
14.80c + 17s = 6

c + s = 6
14.80s + 17c = 91

c + s = 91
14.80s+ 17c = 6

Enterprise charges to rent compact cars for a fixed amount per day plus a fixed amount for each mile driven. Batman rented a car for 6 days, drove it 550 miles and spent $337. Superman rented the same car for 3 days, drove for 350 miles and spent $185. Set up the system. Let "d" represent the fixed charge per day and "m" represent the cost per mile.

6d + 550m = 337
3d + 350m = 185

6d + 550m = 185
3d + 350m = 337

6m + 550d = 337
3m + 350d = 185

6m + 550d = 185
3m + 350d = 337

3e + t = 4.00

2e + 2t = 4.00
3e + t = 4.80
