Question

Pheobe had 6 keys. She paid with a $10.00 bill and received $3.28 change. How much did it cost to have EACH key made

Answer 1

$1.12

Explanation:

One way to solve this problem is through an algebraic equation. Set up the equation like this,
`10-3.28=6x`. This equation works because 3.28 is subtracted from 10, which represents how much was spent in total. Then, this is equal to 6x, which represents the total cost of six keys.

So, to solve first subtract 3.28 from 10, this gives you 6.72. Then, divide both sides by 6. This equals 1.12, which is the cost of each key.
