The expression representing the total value of the coins specified is given by: Option D : 0.05n + 0.10d
How to form mathematical expression from the given description?
You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
For the given case, we've got to find the value of the amount those coins make up together.
The price (in dollars) of specific coins are:
- Nickle= $0.05
- Dime = $0.10
Since, it is given that there are n nickels and d dimes, thus, total amount is
Total amount = $(0.05 + 0.05+ ... + 0.05 (n times)) +
$(0.10 + 0.10 + ... + 0.10 (d times) )
Total amount = $ (0.05 × n + 0.10 × d) = 0.05n + 0.10d in dollars)
(we don't write symbols like of currency generally, and understand it from context. Also, sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together)
Hence, The expression representing the total value of the coins specified is given by: Option D : 0.05n + 0.10d
