Answer:

a) T = 0.25Q + 0.10D

Step-by-step explanation:

One quarter is worth 0.25 dollar.

Q quarters are worth 0.25Q dollars.

One dime is worth 0.10 dollar.

D dimes are worth 0.10D dollars.

The total value of Q quarters and D dimes is the sum of the values of the quarters and dimes.

total value = 0.25Q + 0.10D

Answer: a) T = 0.25Q + 0.10D
