Harry and Ben baked some brownies.
When Harry gave Ben 25 brownies, both of them had the same number of brownies.
If both of them had an average of 155 brownies each, how many brownies did Harry have at first?

Sagot :

Answer:

Harry had 180 brownies at first.

Step-by-step explanation:

1. Total brownies: 155 × 2 = 310

2. Let H be the number of brownies Harry had at first.

3. Let B be the number of brownies Ben had at first.

4. We have:

H +B = 310

H -25 = B+25 or H- B= 50

5. Solve the equations:

H+ B = 310

H-B= 50

6. Add the two equations:

(H + B) + (H -B) = 310 + 50

2H = 360

H = 180
