Brad put 10 crickets in his pet lizard’s cage. After one day, Brad’s lizard had eaten 20% of the crickets he had put in the cage. By the end of the next day, the lizard had eaten 25% of the remaining crickets. How many crickets were left in the cage at the end of the second day?
10 - (10*.2) = ?
? - (? * .25 = ??
Solve for ?, then ??
23
To solve this problem, we need to follow these steps:
Step 1: Calculate the number of crickets the lizard had eaten after one day.
20% of 10 crickets = (20/100) * 10 = 2 crickets
After one day, the lizard had eaten 2 crickets.
Step 2: Calculate the number of crickets remaining after one day.
Remaining crickets = 10 crickets - 2 crickets = 8 crickets
After one day, there were 8 crickets left in the cage.
Step 3: Calculate the number of crickets the lizard had eaten by the end of the second day.
25% of 8 crickets = (25/100) * 8 = 2 crickets
By the end of the second day, the lizard had eaten 2 crickets.
Step 4: Calculate the number of crickets remaining at the end of the second day.
Remaining crickets = 8 crickets - 2 crickets = 6 crickets
Therefore, at the end of the second day, there were 6 crickets left in the cage.
To find out how many crickets were left in the cage at the end of the second day, we can follow these steps:
1. Start with the total number of crickets Brad put in the cage, which is 10.
2. Calculate the number of crickets that were eaten after one day: 10 * 20% = 2. Here, we multiply the total number of crickets by the percentage eaten (20%) to find out how many crickets were eaten.
3. Subtract the number of crickets eaten from the initial total to find the number of crickets remaining after one day: 10 - 2 = 8.
4. Calculate the number of crickets eaten on the second day: 8 * 25% = 2. Here, we multiply the number of crickets remaining after the first day by the percentage eaten (25%) to find out how many crickets were eaten.
5. Subtract the number of crickets eaten on the second day from the number of crickets remaining after the first day to find the number of crickets left at the end of the second day: 8 - 2 = 6.
Therefore, there were 6 crickets left in the cage at the end of the second day.
