To find the total number of coins Jordan has, add the number of dimes and quarters together. If dd dimes and qq quarters are given, the total number of coins will be dd + qq.
Step-by-step explanation:
To find the total number of coins Jordan has, we add the number of dimes and quarters together. In this case, Jordan has 12 dimes and 5 quarters. Therefore, the total number of coins Jordan has is 12 + 5 = 17 coins.
If we have dd dimes and qq quarters, the total number of coins will be dd + qq.
