Four sided figure is a quadrilateral
Answer:
$6
Step-by-step explanation:
This is for one pencil to each student. Since each box is $3, and she has 25 students, you would figure out how many students are left out with one box, and since you only have one left, you only need one more box. That would mean two boxes, so $3x2= $6

Answer:
Final answer is $1280.
Step-by-step explanation:
Given that $250 is invested at an interest rate of 10.3% for 40 years.
Now we need to determine the amount of that investment after 40 years.
It doesn't say anything about compounding period so I will consider that as simple interest.
Hence let's use simple interest formula:

Where amount invested = P = 250
rate of interest = R = 10.3% = 0.103
Time = T = 40 years
Now plug these values into above formula

Hence final answer is $1280.
