Kristen made half as many sundaes as reese if they made thirty sundaes in all how many did kristen make

Well, since half is when you divide something by 2, divide 30 by 2

Then, you get 15

So Kristen made 15 sundaes!

Hope this helped!

Kristen made 10 sundaes because they cant have the same number of made sundaes and the total is 30 and 20+10=30 is correct so therefore kristen made 10 sundaes i think
