The rise in temperature by 11 degrees Fahrenheit can be represented by the temperature change, ΔT = +11 °F. The temperature change is positive because the temperature increased as stated in the question. Moreover, the formula for temperature change is: ΔT = T_final - T_initial. This means that for this case, the final temperature is higher than the initial temperature.

kotegsom [21]

Answer:

The answer to your question is $21.0

Step-by-step explanation:

Data

Original price = $25

Discount = 20%

Taxes = 5%

Process

1.- Calculate the price with the discount

                     $25 ------------------- 100%

                        x   -------------------   20%

                        x = (20 x 25) / 100

                        x = 500 / 100

                        x = $5

Price after the discount = $25 - $5

                                       = $20

2.- Calculate the price after taxes

                     $20 ---------------------- 100%

                         x  -----------------------   5%

                       x = (5 x 20) / 100

                       x = 100 / 100

                       x = $1

Final price = $20 + $1

                = $21
