Step-by-step explanation:
Let
c------> the number of cards in one pack of cards
we know that
After one year,
he had a total of 107 cards in his collection.
Remember that in one year there are 12 months
so
107=12c+11
Solve for c
12c=107-11
12c=96
c=96/12
c=8 cards
One pack has 8 cards
Let
x ------> the time in months
f(x) ------> the number of basketball cards in Stanley's collection
The linear equation that represent this situation is
f(x)=8x+11
Find out the number of cards after 15 years
x=15*12=180 months
substitute
f(180)=8(180)+11=1,451 cards
therefore
The domain of the function is 180 months
The range of the function is 1,451 cards
