Mark is 20. 55 - 15 = 40, 40 / 2 = 20. Mark is 20
Answer:
Step-by-step explanation:
Part A
The discount offered is 30%. If the original price of a sweater is $40, then the discount on the sweater is
30/100 × 40 = $12
The cost of the sweater after the discount is
40 - 12 = $28
Part B
The discount on the shirts was 30%. The amount taken off the shirt is
30/100 × 63 = $18.9
The original cost of the three shirts is
63 - 18.9 = $44.1
Since the shirts are of the same price,the original cost of each shirt is
44.1/3 = $14.7
Part C
Each employee gets an additional 10% off the already discounted price. If an employee buys an item with an original price of $40, then the additional amount taken off is
10/100 × 40 = $4
The amount that the employee would pay is
40 - 4 = $36
it's 8,
let the no. of tired students be x
add all the numbers of the happy, hungry and in between students and then subtract from the total of the student
which has to look smth like this
happy = 10
so we fill all the numbers in between then we add them and see what's missing
1+3+2 = 6
10-6 = 4
4 students are happy
hungry = 7
1+1+3 = 5
7-5 = 2
2 students are hungry
and lastly for tired, they didn't mention the total so we add all the numbers we got and subtract them by the total of students (just like mentioned above)
2+1+1+3+4+2 = 13
21-13 = 8
8 students were tired
x = 8
This would be 14137.17.
V=4/3 x π x r^3 = 4/3 x π x 15^3 ≈ 14137.16694
