The given system of equations models the coins in a jar containing n nickels, d dimes, and q quarters. Which statement is modeled by one of the equations in the system? q is equal to d plus n 0 point 2 5 q plus 0 point 1 0 d plus 0 point 0 5 n is equal to 6 point 0 5 q plus d plus n is equal to 36
Answer
A
There is an equal number of nickels, dimes, and quarters.
B
The total value of the coins in the jar is 36 dollars .
C
The number of nickels is equal to the total number of dimes and quarters.
D
There is a total of 36 coins in the jar.
Explanation
The equation q + d + n = 36 adds the number of quarters, dimes, and nickels. Since each variable counts coins, it states that there are 36 coins in total. The equation with 0.25, 0.10, and 0.05 gives the total value as $6.05, not $36.
