Answer:
10 bugs
Step-by-step explanation:
If last month the spider ate 8 bugs, and this month the spider ate 25% more bugs, we can calculate the amount of bugs the spider ate this month finding how much is 25% of 8 bugs, and them we sum this value to the 8 bugs it ate last month.
25% of 8 = 8 * 25 / 100 = 2
Now we know that the spider ate 2 more bugs, so the amount of bugs it ate this month is 8 + 2 = 10 bugs.
We can also solve this problem multiplying directly 8 by 1.25 (1.25 represents the 25% increase in the bug consumption):
8 * 1.25 = 10 bugs.
Answer: B) 1/6
Explanation: First, we want to add up all the candies, and after doing that we discover that there are 25 candies in total. Next, we take away an orange candy, leaving us with 4 orange candies, but it also takes away 1 from the number of total candies, leaving us with 24 total candies. Finally, we put orange candies as our numerator and total candies as our denominator and get 4/24, which simplified becomes 1/6.
