Translate the word phrase into a math expression.

p= 20x

where p is equal to the number of pens, and x is equal to the number of boxes that Sheila has purchased.

20p

To translate the word phrase "Sheila buys some boxes of pens, with 20 pens in each box" into a math expression, we can use variables.

Let's say the number of boxes Sheila buys is represented by the variable "b". And let's also represent the number of pens in each box by the variable "p".

Then, the math expression would be:

Total number of pens = b * p

In this particular case, since Sheila buys "some" boxes of pens with 20 pens in each box, we don't have specific values for "b" and "p". However, using this expression, you can substitute the specific values into the variables to find the total number of pens in any given scenario.
