Question

You decide to order some baseball cards. Each pack of cards

costs $3.50. The shipping fee is a flat $5.00 no matter how
many cards you order.
If your order came to a total of $50.50, how many packs did
you order?
packs

Answer 1

13 packs

Explanation:

Let's make an equation to represent this situation

The total cost, c, is represented by each pack, p, that costs 3.50, and there is a shipping fee of 5.00 added on no matter what.

3.50p+5=c

We know that the total costs was 50.50, so we can substitute 50.50 in for c.

3.50p+5=50.50

Now, solve for p. To do this, we need to get p by itself. First, subtract 5 from both sides, since 5 is being added to 3.50p.

3.50p+5-5=50.50-5

3.50p=45.50

Next, divide both sides by 3.50, since 3.50 is being multiplied by p.

3.50p/3.50=45.50/3.50

p=13

So, the order had 13 packs of baseball cards
