You deposit some money into a bank account paying 8% simple interest per year. You received $500 in interest after 2 years. How much the deposit (principal) was?
Result
The principal was $3125.
Explanation
Find principal by using the formula I=P⋅i⋅t, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this example I = $500, i = 8% and t = 2 years, so
IPPP=P⋅i⋅t=Ii⋅t=5000.08⋅2=3125
I believe the answer should be 28.

A One-to-One function has only one value of y for a given value of x. Neither x value is paired with more than 1 y value, nor a y value is paired with more than 1 x values.
From the given options, the option A represents a One-to-One function.
In option B, a same y value occurs at more than one values of x. Same can be seen in option C. Therefore, these two are not One-to-One functions.
So, the correct answer is option A.
