Answer:
$157.17
Step-by-step explanation:
Interest is the amount of return that someone receive on the amount invested in a bank or in a business. The annual interest rate is defined on the invested amount. The amount invested is called the principal and.
By applying the interest rate on the principal amount, we can calculate the annual interest earning.
Principal = $3,100
Rate of simple interest = 3.38% per year
Now, define the total time period.
Time period = 18 months = 18 / 12 = 1.5 years
Now calculate the Total interest earning.
Interest Earned = $3,100 x 3.38% x 1.5 = $157.17
So its a square with a side length of 3x so all sides are 3x so 3x x 3x is 9x 9x = 324 so 924/9 is your answer ;D
The statement is contradictory, because it is said that every member of the family gives a gift to every other member of the family. And from 10 members, there are just 2 exchanging. Anyway, maybe they are only 2 members exchanging the gifts at that point in time.
So, each member will exchange 9 gifts (that is 10 members total minus herself), and 2 members are exchanging gifts at that point, so 18 gifts are being exchanged.
