Answer:
$4 is spent on a big pail and $2 is spent on a small pail.
Step-by-step explanation:
Given:
10$ is spent on 2 big pails and 1 small one.
A small pail cost half as much as each big one.
Now, to find the amount spent on a big pail and on a small pail.
Let the cost of a big pail be
And the cost of small pail be
As given, there are 2 big pails.
And the total money spent = $10.
According to question:
Multiplying both sides by 2 we get:
Dividing both sides by 5 we get:
The cost of a big pail = $4.
So, the cost of a small pail =
Therefore, $4 is spent on a big pail and $2 is spent on a small pail.

Enter your answer in the box.
a_12=
a=alan
b=billy
c=charlie
a is 80% more than charlie means that a is 100% and billy=20%, so 20% of alan=billy
0.2a=c
b has 3/5 of c
b=3/5c
if b-150 and c+150, (c+150)=3 times (b-150)
luckily we can related c and b
b=3/5c
c+150=3(3/5c-150)
distribute
c+150=9/5c-450
add 450 both sides
c+600=9/5c
minus c both sides
600=4/5c
times 5/4 both sides
750=c
charlie has 750 stamps
billy=3/5 times c
b=3/5 times 750
b=450
allan has 80% more than billy
0.2a=b
0.2a=450
divide both sides by 0.2
a=2250
b=450
a=2250
c=750
add them
a+b+c=2250+450+750=3450 stamps
Answer:
C
Step-by-step explanation:
square the value the square root is between , that is
4² = 16 and 5² = 25
then the square root must be between the values of 16 and 25
from the list 16 < 24 < 25
That is
