Iuliana 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

0.25(22 – d) + d = 10.75

Step-by-step explanation:

Here, d represents the number of dollar coins,

Since, the total coins = 22,

So, the number of quarts coin = 22 - d,

Also, 1 quarts = $ 0.25

Thus, the cost of 22-d quarts and d dollars = ( 0.25(22-d) + d ) dollars,

According to the question,

Total cost of coins = $ 10.75

⇒ 0.25(22-d) + d = 10.75

Which is the required equation.

Third option is correct.
