$8.16 is the unit rate per hour so just multiply the amount she makes per hour by hours. so there were 8 whole hours. $8.16*8=$65.28. then you have half an hour so $8.16/2=4.08. add. ANSWER: $69.36

Answer:
probability of getting no heads: 1/ 8
probability of at least two tails: 1/4
Step-by-step explanation:
To calculate the probability of getting no heads, multiply the probability of not getting heads for each coin. A coin has two sides: heads and tails; the probability of not getting heads would be 1/2.
1. Multiply the probabilities for each coin
1/2 · 1/2 · 1/2 = 1/8
To calculate the probability of getting at least two tails, multiply the probability of getting tails for two coins and the probability of flipping either heads or tails for the remaining coin. Because it is at least two tails, the remaining coin can flip to either heads or tails.
1. Multiply the probabilities for each coin
1/2 · 1/2 · 2/2 = 1/4
