Betsy gave Rony 150 crayons. Now, Rony has 300 crayons. How many crayons did Rony have before?

• A. 30
• B. 15
• C. 45

Answer 1

The correct option is B 15

Number of crayons that Rony had earlier $=?$
Number of crayons given by Betsy to Rony $=150$
Total number of crayons that Rony has after Betsy gave him 150 more $=300$

? + number of crayons that Rony got from Betsy = total number of crayons that Rony has
$⟹$ ? + 150 = 300

Number of crayons Rony had earlier $=300–150=150$
