Spencer took 21$ with him to the mall. At the music store, he spent 2/3 of his money on a DVD, he spent 1/4 of what he had left on a drink. How much did spencer have left after he bought the drink?

$5.25 Dollars

Step-by-step explanation:

I know that if you divide 21 by 3 you get 7. So, 2/3 of 21 is 14. He spent 14 dollars at the music store. This means that he has 7 dollars left. From here he spend 1/4 of 7 dollars on a drink. 1/4 of 7 is $1.75. This means that he has 5.25 dollars left after he bought the drink! :)

Hope this helped! :)

Since the question states that one frog has a mutation, it doesn’t say whether it is less or more poisonous, but it does state that there is a mutation, therefore D would be the correct answer since there has been a change in the frogs genes.
