Question

Write the following as an expression.

I have 10 pounds of nuts worth $d per pound. What is the value of the nuts?​

Answer 1

10d
it's basically 10 times $d

Answer 2

$10d

Explanation:

The unit price is $d per pound. It is a dollar amount divided by the number of pounds. If you multiply the unit price by pounds, then the units work out like this:

$/lb * lb = $

When you multiply the unit price in dollars per lb by lb, you get dollars.

In your case:

$d/lb * 10 lb = $10d

That value of the nuts is $10d.
