nth term of an AP is
Substitute and in the above formula.
It represents the amount deposited into the account after n birthdays.
We need to find the amount by her 18th birthday.
Put n=18 in the above equation.
Therefore, $475 deposited into the account on her birthdays by her 18th birthday.
23,456
x 86
If we calculate the conventional way,
This gives us 23,456 * (6 + 80)
= (23,456 * 6) + (23,456 * 80)
First, we multiply 23456 by 6, the figures obtained will be 140736 (which is given in the question)
Next, we multiply 23456 by 80, the figures obtained will be 1,876,480
The third option is the correct answer
Answer:
Let the additional weight that can be added be = x
Current weight of the bag = 38 pounds
Total weight can be = 50 pounds
