Question

Which expression represents the value, in dollars, of a certain number of quarters, q, and dimes, d? 0.35qd 0.35q + d 0.10q + 0.25d 0.25q + 0.10d

Answer 1

Answer:

0.25q + 0.10d

Step-by-step explanation:

We know that each quarter values 0.25 dollars, therefore the amount in dollars of q quarters would be 0.25q.

On the other hand, each dime has a value of 0.10 dollars, therefore the amount in dollars of d dimes would be 0.10d

If we have both quarters and dimes, we would need to sum up the previous two expressions: 0.25q + 0.10d would be the value in dollars of this.

Answer 2

That would be 0.25q + 0.10d because you want to multiple the number of quarter by 0.25 to determine how much you have with quarters, and the number of dime by 0.10 for dimes.

Then you add together, hence 0.25q + 0.10d.
