I = prt is the formula for simple interest
400 = 8000* .02 * t
400 = 160 * t
2.5 = t
2.5 years to earn $400 interest
The correct answer is B) y = 120000x + 420000.
We multiply 120,000 by x since that is the cost per person per day, and x is the number of days. We add 420,000 because that is the one time cost of the round trip airfare.
HCF=Highest Common Factor-HCF of two or more numbers is the greatest factor that divides the numbers. For example, 2 is the HCF of 4 and 6.
LCM=Least Common Multiple-LCM is the smallest positive number that is a multiple of two or more numbers.

Answer:
Option A is the answer.
Step-by-step explanation:
We have been given the ordered pairs.
The function is a representation

For a mapping to be a function there should always be a unique value of y for different values of x.
So the mapping :
(-4,-2) (-1,3) (0,3) (5,-6)
3 has two different values hence not a function.
Therefore, Option A is the answer.
