"The product" immediately suggests multiplication; we're going to be multiplying two quantities together, "3" and "a number minus 7"
"A number" just describes an unknown value, so we'll pick the letter n to be that unknown in our expression. "A number minus 7" then could be written as n - 7.
We can now write the product of 3 and (n - 7) as the expression
3 × (n - 7)
The expression that represents 'the product of 3 and the quantity of a number minus 7' can be written in algebra as 3*(x - 7). Here, x is our variable and can be any number.
The student is asking for an expression that represents 'the product of 3 and the quantity of a number minus 7'. In terms of algebra, this can be expressed in the following way: assuming the 'number' is represented by a variable, like x, we can write it as 3*(x - 7).
This mathematical expression says that we first subtract 7 from our number, x, and then multiply the result by 3.
For example: if x is 10, we would first calculate 10 - 7, which is 3, and then multiply that result by 3, yielding a final product of 9.

If 1 inch = 94 feet, 4 inches is 94 × 4.
94 × 4 = 376
Add 376 to itself 5 times, or use a simpler method and multiply 376 by 5.
376 + 376 + 376 + 376 + 376 = 1,880
376 × 5 = 1,880
The perimeter is 1,880 feet. (20 without the scale applied)
