Can't get started on this for my granddaughter:

Question

Grace had 3 times as many berries as Tyler. After Grace eats 50 berries she has half as many berries as Tyler. How many berries does Grace have left.

Answer 1

So if 50 is half of what Tyler had then he had 100. Grace had 3 times
Tyler so that would be 300. She ate 50 so she has 250 left (and a very bad stomach ache). If this is even correct is there some algebraic way to show the work??? This is just for a 4th grader and I have no idea how the teacher wants the problem worked.

Answer 2

No, don't think what I wrote before is correct.

Answer 3

Assume: Tyler had x berries.
so, Grace has 3x berries.

Now after Grace eats 50 berries, we have the following equation:

3x - 50 = x/2
6x - 100= x
5x = 100
x = 20

Grace had left with 10 berries.

Answer 4

Thank you so much Yrafaj!!! Robin
