Answer:
$38.50
Step-by-step explanation:
⇒ Find 30% of 55:
30% of 55 = 16.5
⇒ But that’s not the answer. That’s 30% of 55. The question says it’s 30% <em><u>off</u></em>. So you need to subtract 16.5 from 55:
55 – 16.5 = 38.5
⇒ You can also see that you can just straight up do 70% of 55:
70% of 55 = 38.5
<u>Answer:</u> $38.50

Answer: -6
Step-by-step explanation:
A.) If there are no restrictions, Number of committes possible = 9C5 = 126
b.) If both Jim and Mary must be in the committee, then we are now choosing 3 persons from the remaining 7 people. So the number of committes possible = 7C3 = 35
c.) If either Jim or Mary (but not both) must be on the committe, then there are 7 people availabe and 4 choices to make after taking either Jim or Mary. Also, there are 2 possible ways of choosing either Jim or May.
Theefore, Number of committe possible = 2(7C4) = 2(35) = 70
The percentage of questions she got correct is 88%
