Given :
At a restaurant, Brianna and Naomi each order an appetizer for $6.50 and an entree for $9.75.
The sales tax is $0.98 and they leave a tip of $5.85.
To Find :
How much did Brianna and Naomi spend in all.
Solution :
Total expenses, T = Food + tax + tip
T = $( 6.50+9.75) + $0.98 + $5.85
T = $( 16.25 + 0.98 + 5.85 )
T = $23.08
Therefore, total expenses is $23.08 .
Hence, this is the required solution.
Answer:
1/30
Step-by-step explanation:
6 white marbles
5 red marbles
+ 19 marbles of other colors
-----------------------------------------------
30 marbles in total
First drawing:
p(white) = (number of white marbles)/(total number of marbles)
p(white) = 6/30 = 1/5
Second drawing:
Since the first marble is replaced, there are still 30 marbles in the bag.
p(red) = (number of red marbles)/(total number of marbles)
p(red) = 5/30 = 1/6
The two drawings are independent events, so the overall probability of the two events is the product of the individual probabilities.
p(white then red) = p(white) × p(red)
p(white then red) = 1/5 × 1/6
p(white then red) = 1/30
I believe that the answer to that problem is d
