kristin spent $131 on shirks fancy shirts cost $28 and plan shirts cost $15 if she bought a total of 7 how many of each kind did she buy

Answer 1

28F +15P = 131

F + P =7

15F+15P =105 subtract from the 1st equation to get

13F = 26

F = 2 fancy shirts

P =5 plain shirts

28(2) + 15(5) = 56+75 = 131
