Question

Domingo had 250 baseball cards, andJennifer had 82 baseball cards. At thefirst meeting of the Card Club and atevery meeting thereafter, Domingo sold12 cards to Jennifer. After which meetingdid the two have the same numberof cards?

Answer 1

Data:

Domingo: D

Jennifer: J

Initial number of cards:

D=250

J=82

After each meeting(m):

D=250-12m

J=82+12m

After the first meeting: m=1

`D=250-12(1)=238`
`J=82+12(1)=94`

You increase in 1 the m after each meeting and get the next table:

Then, they have the same number of cards after 7th meeting
