Answer:

Step-by-step explanation:
Probability of getting a 7 + Probability of not getting a 7 = 1.
Odds against drawing a 7 = Probability of not getting a 7.
We could calculate the probability of getting a 7 and subtract 1 from it to get the answer.
There a four sevens in a deck of card, one of each kind.
Probability of getting a 7 = 

P(not getting a 7)
Janine = J = 15
Leah = L = ?
L = J + 6
L = 15 + 6
L = 21
So Leah spent $21

Answer:
Step-by-step explanation:
-5f=-3(8-f)
Opening bracket
-5f = - 24 + 3f
Collecting like terms
-5f - 3f = -24
-8f = -24
Dividing by -8
f = -24/-8
f = 3
