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? o d - 22 + 0.25d = 10.75 o 0.25d + 22 - d = 10.75 o 0.25(22 - d) + d = 10.75 o d + 0.25(d - 22) = 10.75

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? o d - 22 + 0.25d = 10.75 o 0.25d + 22 - d = 10.75 o 0.25(22 - d) + d = 10.75 o d + 0.25(d - 22) = 10.75

Answer

Answer:

C. $0.25(22 - d)+d = 10.75$

Explanation:

Step1: Define the number of quarters

The total number of coins is 22. If the number of dollar - coins is $d$, then the number of quarters is $22 - d$.

Step2: Calculate the value of quarters and dollar - coins

A quarter is worth $0.25$ dollars and a dollar - coin is worth 1 dollar. The total value of quarters is $0.25(22 - d)$ dollars and the total value of dollar - coins is $d$ dollars.

Step3: Set up the equation

The total value of all coins is $10.75$ dollars. So, the equation is $0.25(22 - d)+d = 10.75$.
