Answer:
A sandwich shop offers:
Bread: 1 , 2
Meat: 1 , 2 , 3 , 4
Cheese: 1 , 2 , 3
Choose one to be your starting point. For example, choose Bread. You only choose one of each, so:
Bread 1, Meat 1, Cheese 1
Bread 1, Meat 1, Cheese 2
Bread 1, Meat 1, Cheese 3
etc. etc.
However, note that there is an easier way to solve it. In this case, you can use the <em>Fundamental Principle of Counting</em>, which each total number of choices are added together.
Multiply them:
Bread x Meat x Cheese = 2 x 4 x 3 = 24
There are 24 different types of sandwiches that can be made if only one of each is chosen.

Answer:
Answer is A $172.25
Step-by-step explanation:
Step 1: Our output value is 575.50.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$575.50=100\%$.
Step 4: Similarly, $x=30\%$.
Step 5: This results in a pair of simple equations
$575.50=100\%(1)$.
$x=30\%(2)$.
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
$\frac{575.50}{x}=\frac{100\%}{30\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{575.50}=\frac{30}{100}$
$\Rightarrow x=172.65$
Therefore, $30\%$ of $575.50$ is $172.65$
Answer:
34 - 25 = 9
Step-by-step explanation:
It would be B because 64.35/7.15=9 so e=9
