Cole went trick or treating on halloween. he ate 10% of his candy the next day. if he ate 25 pieces of candy the next day, how many pieces of candy did he collect on halloween?

Offering 30 if a plus b plus c equals 68 and ab plus bc plus ca equals 1121, where a, b, and c are all prime numbers, find the value of abc. the answer is 1978 but i need an explanation on how to get that.

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
