28-10= 18
Now, divide that by 3. (for her three friends)
18/3= 6
Each friend got 6 erasers.
I hope this helps!

Answer:
D.)
Step-by-step explanation:
y = 5/x
so when the value of x triples, the new X becomes;
X = 3x
So,
Y = 5/ X
=> Y = 5/3x
=> Y = 1/3 . 5/x
=> Y = 1/3 . y
so the new value of y ( Y ) is 1/3 times original y.
Hence, D. is the answer
No, it's not written in scientific form because it has to be like this :
#1-10•10^#
So for 1, A is correct.
2. 1.22•10^8
3. 2.87•10^-2
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
