Question

Jane buys 3 magnets and 9 bookmarks at a craft fair. The magnets cost $5 each, and the bookmarks cost $2 each. Which equations can be used to find how many dollars, d, Jane spends at the craft fair? Choose all the correct answers.​

Answer 1

Choice A and C

Explanation:

If 1 magnet costs $5, then 3 magnets cost $15 because adding 3 magnets to your bag, would equal to 5+5+5, or 5x3. If 1 bookmark cost $2, then 9 bookmarks would cost $18 to your bag, which would equal 9+9, or 9x2.

So, C is correct because 5x3 is 15, and 2x9 is 18. A is also correct because it's just the other way around, 2x9=18 and 5x3=15.
