Question

Please help!! Which is correct

Answer 1

3rd

Explanation:

Just look at the second equation in each system (no need to look at the others). The third is the only one that makes sense. The total value means the number of coins multiplied by value of each. The value in dollars is $9.35

If the value in the equation is in dollars, the variables must be multiplied by values in dollars. You can't multiply with 5 cents per nickle to equal 935 dollars. Makes no sense.

Answer 2

C

Explanation:

• The difference between the dimes and quarters is 3.
• There are more dimes than quarters.
• Therefore the equation that expresses that fact is
• d - q = 3

• The number of coins is 94
• n + d + q = 94

• The value of the coins is 9.35
• The equation is
• 0.05n + 0.10d + 0.25q = 9.35

The Answer is C
