Last week, an office group spent $122 on 6 cheese pizzas and 4 salads. This week, the group spent $192 on 8 cheese pizzas and 6 salads. Let c represent the number cheese pizzas and s represent the number of salads. Which system of equations can be used to find the cost of one cheese pizza and one salad? 6 c + 4 s = 122. 8 c + 6 s = 192.
6 c + 4 s = 192. 8 c + 6 s = 122.
8 c + 4 s = 192. 6 c + 6 s = 122.
4 c + 6 s = 122. 6 c + 8 s = 192.
