Answer:
There are 20 students in the class
Step-by-step explanation:
Let the total number of children in the class be = x
from the question, we know that 20% of all the children are left-handed. We also know that 20% of the total children in the class = 4.
This means that 20% of x = 4
Wherever we see the word "of" in an arithmetic problem, we should know that it infers a multiplication there.
Hence, we have


There are 20 children in the class altogether
Answer: $1090
Step-by-step explanation:
Since Caroline won $205000 in a lottery and then paid $96000 in taxes, the remaining amount will be:
= $205000 - $96000
= $109000
The interest that the account will earn after just 6 months will be:
Interest = PRT
= 109000 × 2% × 6/12
= 109000 × 0.02 × 0.5
= $1090
