Answer:

$\large \boxed{\mathbf{56.06 \, \% }}$

Step-by-step explanation:

1. Calculate the dollar depreciation

Original price = $965

Present value = 424

Depreciation = $ 541

2 Calculate the rate of depreciation

The phone has depreciated for one year.

$\begin{array}{rcl}\text{Rate of depreciation} & = & \dfrac{\text{Depreciation}}{\text{Original price}} \times 100 \, \%\\\\& = & \dfrac{\text{541}}{\text{965}} \times 100 \, \%\\\\& = & \dfrac{\text{541}}{\text{965}} \times 100 \, \%\\\\& = & \mathbf{56.06 \, \%}\\\\\end{array}\\\text{ The rate of depreciation is $\large \boxed{\mathbf{56.06 \, \% }}$ per year}$

There are 58 students enrolled in an art class. The day before the class begins, 10.3% of the students cancel. How many students

Sidana [21]

First, set up a proportion. 10.3% is the percentage of students who cancelled, but the question is asking for the students who are attending, so let’s use 89.7% to make it easier. The proportion would be x over 58 is equal to 89.7% over 100%. Multiply 58 by 89.7, giving you 5,202.6. Next, take 5,202.6 and divide it by 100. This should give you 52. 026, but it’s best to round this to 52. 52 students actually attend the art class, making this your final answer.
