Solution

Solution Steps

To solve this problem, we need to perform a series of arithmetic operations on the initial price of an appliance. For each operation, we will calculate the new price based on the given mathematical expression. The operations are as follows: add 15 to the initial price, subtract 15 from the initial price, multiply the initial price by 100, divide the initial price by the sum of 15 and 100, and divide the initial price by the difference of 15 and 100.

Step 1: Calculate

E

To find the new price $E$ , we add 15 to the initial price: $E = 200 + 15 = 215$

Step 2: Calculate

D

To find the new price $D$ , we subtract 15 from the initial price: $D = 200 - 15 = 185$

Step 3: Calculate

C

To find the new price $C$ , we multiply the initial price by 100: $C = 200 \times 100 = 20000$

Step 4: Calculate

B

To find the new price $B$ , we divide the initial price by the sum of 15 and 100: $B = \frac{200}{15 + 100} = \frac{200}{115} \approx 1.7391$

Step 5: Calculate

A

To find the new price $A$ , we divide the initial price by the difference of 15 and 100: $A = \frac{200}{15 - 100} = \frac{200}{-85} \approx -2.3529$

Final Answer

The new prices are:

$E = 215$
$D = 185$
$C = 20000$
$B \approx 1.7391$
$A \approx -2.3529$

Thus, the final boxed answers are: $\boxed{E = 215, D = 185, C = 20000, B \approx 1.7391, A \approx -2.3529}$
