Hello!
We are told that the Father’s Day gift was $75, the cost of which was split between three people. This can be represented using the following equation:
(Beth) + (James) + (Buzz) = $75
We know that Beth and James each contributed $25. Now we can rewrite the equation with the given information and then simplify:
$25 + $25 + (Buzz) = $75
$50 + (Buzz) = $75
Now subtract $50 from both sides and simplify:
$50 (-$50) + (Buzz) = $75 (-$50)
Buzz = $25
We have now proved that Buzz contributed $25.
I hope this helps!
