Step-by-step explanation: First, you need to write all your data down from least to greatest. Next, count up all the numbers to see how many students. Then you want to find the mean which is average (add then divide). Median is the middle so you will x each number out till you get to the middle, and if the middle is 2 numbers, you find the average of them to find the median. Mode means most often. Range is highest minus lowest. And you can do the next 2.
The present worth of the loan is <span>$6,250 </span>The start of payment will after 4 years The nominal interest rate is 6.1% compounded monthly which is equal to 6.27% effective.
The future worth (after graduation) of the loan is F = <span>$6,250 (1 + 0.0627)^4 = $7,971.18
The interest is </span>$7,971.18 - $6,250 = $1,721.18 I didn't round off when solving these so it's not the exact answer among the choices but the closest is letter B <span>$1,722.22</span>
Let's call A the amount of first type of fruit drinks. 55% pure fruit juice
Let's call B the amount of second type of fruit drinks. 80% pure fruit juice
The resulting mixture should have 65% pure fruit juice and 80 pints.
Then we know that the total amount of mixture will be:
Then the total amount of pure fruit juice in the mixture will be:
Then we have two equations and two unknowns so we solve the system of equations. Multiply the first equation by -0.8 and add it to the second equation:
+
--------------------------------------
We substitute the value of A into one of the two equations and solve for B.
