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

Question

which system of the equations can be used to find the cost of one cheese pizza and one salad?

Answer 1

There does seem to be something wrong with the amounts paid for the two orders of 6 pizzas and 4 salads, and 8 pizzas and 6 salads. The price of salad works out to $44 and that of pizza works out to be $-9. These prices do satisfy the amounts paid. Any other prices would change the amounts paid. I suppose question needs to be rechecked.
