Answer:

  • d + q = 44
  • 0.10d +0.25q = 8.30

Explanation:

The first equation describes the total number of coins. It says the sum of the numbers of dimes and quarters is 44, the total number of coins.

__

The second equation describes the total value of the coins. It will say that 0.10 times the number of dimes plus 0.25 times the number of quarters is 8.30, the total dollar value of the coins.

The two equations are ...

d + q = 44

0.10d +0.25q = 8.30

__

Additional comment

The solution can be found by substituting for d:

0.10(44 -q) +0.25q = 8.30

0.15q = 3.90

q = 26

d = 44 -26 = 18

Vinnie has 18 dimes and 26 quarters in his bag.
