ms. Heinz spent 12 dollars on 30 tokens for the field trip. What was the cost of 12 tokens

Answer 1

If I did the math right the answer should be $4.80.

I got that by setting up a ratio. Then I did the math for this equation...

12x12=30x

144=30x

which if I did the math correctly means she spent $4.80 for her 12 tokens.

That means that each token was worth 40 cents. Thanks that was fun!
