Question

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

Answer 1

We know that 1 quarter = $0.25

Also, there are 22 quarters and dollar coins and together their value is $10.75.

q + d = 22

or :  q = 22 - d

0.25 q + d = 10.75

Finally:

0.25 ( 22 - d ) + d = 10.75

Other equations are wrong.

Answer:
