Answer:

<h2>Second table</h2>

Step-by-step explanation:

One-to-one function is a function that preserves distinctness: it never maps distinct elements of its domain to the same element of its codomain. Every element of the function's domain is the image of at most one element of its domain.

First table:

No. Because for x = 7.25 and x = 8.5 we have the same value of y = 11

Second table:

Yes. Because for all values of x we have different values of y.

If number of nickel = n
number of dimes = 3n
number of quarters = 2n

Amount of nickel = 5n
Amount of dimes = 30n
Amount of quaters = 50n

Total Amount = 5n + 30n + 50n = 510
