Question

Express the answer to this word problem algebraically, using c to represent the number of cards Jack will swap. 'Jack has 165 football cards. He has 6 complete teams of 12 and a further 78 cards he will keep. He will swap the other cards.

Answer 1

Answer:

165-[6(12)+78] = c

and

165-c = [6(12)+78]

Step-by-step explanation:

165-[6(12)+78] = c is explained:

He has 165 cards, subtract the 6 groups of 12 (6 x 12) and the extra 78 to get c, so we have [6(12)+78] subtracted from 165.

165-c = [6(12)+78] is explained:

He has 165 cards, subtracting c will give you the rest of the cards (that he will keep), and so, 165-c = [6(12)+78] (the rest of the cards)
