Peter had a sachet of candy. He wanted to share it with his friends. If he gave them 30 candies, he would have 62 candies. If he gave them 40 candies, he would miss eight candies. How many friends did Peter have?

Correct answer:

n =  7

Step-by-step explanation:

30n +62 = 40n - 8

30·n +62 = 40·n - 8

10n = 70

n = 70/10 = 7

n = 7
