Eliza is playing roulette on her computer for play money. To play, she “spins” a wheel that consists of 18 red numbers, 18 black

numbers, and 2 numbers that are neither red nor black. Before spinning, she bets $7.60 that the number will come up black. If she wins, she gets back the amount she bet plus $7.60, and if she loses, she must forfeit the amount she bet. If she spins the wheel many times, making the same bet each time, how much can she expect to lose per spin, on average?

Answer:

Step-by-step explanation:

To Find: Interpret the meaning of each term in the expression.

Solution:

14 denotes the number of members

x is the number of minutes after the first minute of the fair

22 denotes each handed out 22 flyers per additional minute of the fair.

350 =25 \times 14 denotes  each handed out 25 flyers during the first minute of the fair.

So, option A is true .
