Answer:
Step-by-step explanation:
Sam bought a chocolate. He ate some and leaving 0.75 for Alice.
Alice ate 18.50 grams of chocolate and return the rest to Sam, which was 65% of the original chocolate. How much chocolate did Sam had at the beginning?
Now solve the equation:
0.75x - 18.50 = 0.65x
Combine the like terms:
0.75-0.65x = 18.50
0.1x= 18.50
x = 18.50/0.1
x=185
This shows that Sam had 185 grams of chocolate...
