D. Multiply the number of packages she has left by the number of beads in each package. So, she has [] beads left.

Step-by-step explanation:

There were a total of 70 packages.

With 18 beads in each package.

And we are told that the teacher distributes 40 packages to students to use them.

To calculate how many spare packages are left we shall

-: Deduct the number of distributed packages from the total packages = (A)

And to calculate the number of beads left:

-: Multiply the value in (A) above with the number of beads in each package.

That is

70 - 40 = 30 = (A)

Now, number of beads = (A) 18 {number of beads in each package}

= 30 18 = 540 beads

The steps followed are similar to option D, thus, it is the correct option.
