Marcella bought 3 packages of balloons and 4 packages of favors for $14.63.
Rupert bought 2 packages of balloons and 5 packages of favors for $16.03. Find
the price of a package of balloons.

Answer:

$1.29 for balloons

Step-by-step explanation:

3b + 4f = 14.63

2b + 5f = 16.03

2b = 16.03 - 5f

b = (16.03/2) - 5/2f

3b + 4f = 14.63

3[(16.03/2) - 5/2f] + 4f = 14.63

48.09/2 - 15/2f + 4f = 14.63

24.045 - 15/2f + 8/2f = 14.63

24.045 - 7/2f = 14.63

-7/2f = -9.415

-3.5f = -9.415

f = 2.69 = $2.69 for favors

2b + 5(2.69) = 16.03

2b + 13.45 = 16.03

2b = 2.58

b = 1.29 = $1.29 for balloons

At the start of a soccer game, the referee flips a coin to determine which team gets the ball first. The referee making
the calls for your upcoming game has seen the last 5 coin flips come up tails. The team captain plans to call heads
during the coin flip because he says it is long overdue.
Is your friend's reasoning correct?
O Yes, the coin flip is more likely to come up heads in order for the probability of heads to get back to 0.5.
No, it is highly unlikely to get 5 tails in a row by chance alone, so the friend should continue to go with tails. This
referee must be using an unfair coin.
O No, the probability of getting heads or tails is 0.5, regardless of the outcomes of the previous flips.
Yes, after so many tails in a row, the coin is due to show heads.
