Each dime is worth 0.10 dollars and each quarter is worth 0.25 dollars. So the total amount of money in the register can be found by multiplying the number of dimes by 0.10 and the number of quarters by 0.25 and then adding the two products. This gives the expression:

0.10(25) + 0.25x = 2.5 + 0.25x

So, the correct expression is C.

A Cash Register Contains 252525 Dimes and X Quarters 250+25x250 + 25 x250+25x

A Cash Register Contains $25$ Dimes and X Quarters $250 + 25 x$
