Answer: 17 nickels, 8 dimes

Step-by-step explanation:

Since we are given system of equations, we can use elimination method to find n or d. First, let's eliminate n. To do so, we need to make sure they are equal to each other. Then, we would have to multilpy the second equaiton by 0.05.

0.05N+0.1D=1.65

0.05N+0.05D=1.25

Now, we can subtract the 2 equations.

0.05D=0.4

D=8

Now that we know the number of dimes, we can plug it into any of the equations to find nickels.

N+8=25

N=17

There are 17 nickels and 8 dimes.

The function m=30-3r represents the amount m (in dollars) of money you have after renting r video games.
san4es73 [151]
The domain of the equation are all the possible values of the independent variables that would make the equation reasonable, possible or true. In this item, the independent variable is r. This could take a value of 0 up to the point when m is equal to zero.
        m = 30 - 3r = 0
              r = 10

The domain is therefore [0, 10]. 

The range is the value of the dependent variable which would be from 0 to the point when no video game is played. This is, [0, 30]. 

The function is discrete because r and m cannot take every value in the number line.
