i think it's 0.25•10+0.1•d=4.90

Remark

4.90 is all by itself. It is the total amount of money.  It should not be multiplied or divided by anything. So A is wrong.

B: requires a decimal place somewhere in the 490. It would take quite a few dimes to make up 490 dollars. B is wrong.

C: 25 is a decimal (0.25) without a multiplication by 10 present. The 25 should not be alone in any event. C is wrong.

D: is the correct answer. It is what you must use to find out how many dimes there are. Although did not ask for it, you need 24 dimes.
