**math lover**, Sunday, May 12, 2013 at 9:55pmlet's use T for tomato and M for mushroom,Stacey:$10.64 is 80% of the original price of 7T and 15M so 20% discount will equal to 2.66 and the original price will be 13.3.

Brian:7.21 is 70% of the original price of 17T and 5M so 30% will equal to 3.09 and the original price will be 10.3.

Stacey:7T+15M=13.3

Brian:17T+5M=10.3

now multiply Brian by 5 will get

7T+15M=13.3

51T+15M=30.9

now subtract it will get

44T=17.6 and T=$.40 and M=$.70
