Shari gets an allowance of $20 per week. she has decided she needs more money, so she has made a deal
with her mother in hopes of increasing her weekly allowance. she proposes that she will throw a dart at
the dart board. if she hits the board, she gets the original $20 plus another shot at the dartboard for
an additional $20. if she misses the first throw, she only gets $10 for the week. shari hits the dart
board 50% of the time.
7. shari's mom is worried about how often she will be giving her daughter $40 a week. given shari's
stats, how many weeks will her mom be out $40?
a) 26 weeks
b) 13 weeks
c) 50 weeks
d) 2 weeks

50% of the given time period. (number of weeks x 0.50)

Step-by-step explanation:

I didn't see the listed time period, so how ever many weeks they wagered, Multiply that by 0.50, since Shari hits the board 50% of the time.

Without a given time period, there is no way for me to choose form the given answers. I need to know the duration of the bet.

If it were 80 weeks, Shari's mom would give her $40 for 40 weeks.

If it were 120 weeks, Shari's mom would give Shari $40 for 60 weeks.

You see the pattern? :)
