Giuliana has 22 quarters and dollar coins worth a total of $10.75. Which equation can be used to find d, the number of dollar coins Giuliana has? d - 22 + 0.25d = 10.75 0.25d + 22 - d = 10.75 0.25 (22 - d) + d = 10.75 d + 0.25 (d - 22) = 10.75

Option (3). 0.25 (22 - d) + d = 10.75

Step-by-step explanation:

Total number of coins Giuliana has = 22

Let the number dollar coins Giuliana has = d

Number of quarters with Giuliana = (22 - d)

Value of dollar coins and quarters = $10.75

So the equation will be,

Number of dollars coins * $1 + Number of quarters * $0.25 = $10.75

d + 0.25 * (22 - d) = 10.75

Therefore, to determine the number of dollars with Giuliana equation will be used,

d + 0.25 (22 - d) = 10.75

Option (3) will be the answer.
