Answer:
C
Step-by-step explanation:
We are given
The student council earned $1.25 for every cup of hot chocolate it sold
and $0.75 for every cup of apple cider it sold
total number of cup is 375
We can see that first term is 1.25x
and we have
The student council earned $1.25 for every cup of hot chocolate
so, to find total cost of hot chocolate , we multiplied 1.25 with x
that's why
x must be the number of cups of hot chocolate sold
So the answer must be C
Answer:
the answer is B
Step-by-step explanation:
Answer: $7.90
Step-by-step explanation:
When we see how much she spent on the total cost of renting skates, getting in, and getting hot chocolate, we can see that she is going to subtract all of that from the total cost.
$15.00 - 2.25 = 12.75
12.75 - 2.15 = 10.60
10.60 - 1.35 = 9.25
9.25 - 1.35 = 7.90 remaining
We know that she payed 2.25 to get in, 2.15 for skate rental, and 1.35 for each hot chocolate she purchased which in this case is 2. We need to subtract all of this from 15 and get the final answer
Answer:
The probability of picking two consecutive purple marbles without replacement is 14.72%.
Step-by-step explanation:
Initially, there are 4+6+2+8 = 20 total marbles.
The probability of picking a purble marble is
P_{1} = \frac{number of purple marbles}{number of total marbles}
P_{1}= \frac{8}{20} = 0.4
Since there are no replacements, there are now 19 total marbles, 7 of which are purple. So, the probability of picking another purple marble is
P_{2} = \frac{7}{19} = 0.368
The probability P of picking a purble marble(P_{1}), not replacing it, and then picking another purple marble(P_{2}) is:
P = P_{1}*P_{2} = 0.4*0.368 = 0.1472 = 14.72%
