Paula bought boxes of thank you cards and get well cards. The thank you cards came in boxes of 5 and the get well cards came in boxes of 4. Paula bought 9 boxes and got a total of 41 cards. How many boxes of each type of card did she buy?
call a box of Thank you cards "T"
call a box of Get well cards "G"
T + G = 9 –> G = 9 – T (eq 1)
5T + 4G = 41 (eq 2)
5T + 4 (9 – T) = 41
5T + 36 – 4T = 41
T = 41 – 36
T = 5
T + G = 9
5 + G = 9
G = 9 – 5
G = 4
