Question

Instructions: Write a linear equation in one variable to help you answer the question.

You're planning to place an order from an online boutique. Leggings (1) are $12 each and shipping is a flat rate
of $5. If your total was $41, how many pairs of leggings did you buy? (Just set up the equation that would help
you answer that question.)

Answer 1

Explanation:

If the leggings are $12 each, and L represents the number of pairs of leggings, the cost of the leggings is 12L. That is the slope of the equation. For each pair of leggings you buy, you're spending another $12. Regardless of how many pair you buy, the shipping will not change. It will be $5 whether you buy 1 pair of leggings or 100 pair. All of these pairs of leggings, L, at $12 apiece plus the $5 shipping added up to $41. Therefore, the equation for this situation is

$41 = $12L + $5
