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...
