To determine the number of items in each of the packages, we simply multiply the number of packages and the number of items in each package.
(1) For the 4 packages of napkin.
(4 packages)(28 napkins/package) = 112 napkin
(2) For 2 packages of cups
(2 packages)(24 cups/package) = 48 cups
From the calculated values, it may be concluded that 4 packages of napkin will have more number of items.
b. By how much?
D = 112 - 48 = 64
<em>Answer: 64</em>
Question: What is 35 percent of 40?
Percentage solution with steps:
Step 1: Our output value is 40.
Step 2: We represent the unknown value with $x$x.
Step 3: From step 1 above,$40=100\%$40=100%.
Step 4: Similarly, $x=35\%$x=35%.
Step 5: This results in a pair of simple equations:
$40=100\%(1)$40=100%(1).
$x=35\%(2)$x=35%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{40}{x}=\frac{100\%}{35\%}$
40
x=
100%
35%
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{40}=\frac{35}{100}$
x
40=
35
100
$\Rightarrow x=14$⇒x=14
Therefore, $35\%$35% of $40$40 is $14$ B. 14%
Answer:
The left cups = (x - 30). → x = 630 cups. Hence, the total number of cups before their usage = 630 cups
Each piece is 20 inches long.
Step-by-step explanation:
The length pieces of the ribbon can be obtained by dividing the total length of ribbon by total number of pieces
Given
String length = 168 inches
Number of pieces = 6
So the length of each piece will be:

Cutting 8 inches from each piece means that the length will be reduced 8 inches

Hence,
Each piece is 20 inches long.
