Question
oshua had a total of 32 pencils and erasers at first. He exchanged all his pencils for erasers. He had 48 erasers after exchanging every 1 pencil for 2 erasers. How many erasers did he have at first?Number of erasers: _____Next
Solution
To solve this problem, we need to find out how many pencils Joshua had at first.
Step 1: We know that after exchanging, Joshua had 48 erasers.
Step 2: We also know that for every pencil he exchanged, he received 2 erasers. So, if we divide the total number of erasers he had after exchanging by 2, we will find out how many pencils he had.
48 erasers ÷ 2 = 24 pencils
Step 3: Now, we know that Joshua had 24 pencils and the total number of pencils and erasers he had at first was 32.
Step 4: To find out how many erasers he had at first, we subtract the number of pencils from the total number of pencils and erasers.
32 - 24 = 8 erasers
So, Joshua had 8 erasers at first.
