Answer:
$531.25 per month
Step-by-step explanation:
$25,500 * 0.75 = $19,125 amount of paid tuition
$25,500 - $19,125 = $6,375 remaining tuition
$6,375/12 = $531.25
This is a combination problem, as the order is not important... So:
There are a total of 6 people, and 4 options available....
n = 6 and r = 4....
Using the combination formula: C(n,r) (Simply use a calculator online or your own)....
C(6,4) = 15.
Construct an equation in which s is the number of tons of sugar to be transported 4500 + 150.25s = 3696 + 200.5s Solve for s 4500 - 3696 = 200.5s - 150.25s 804 = 50.25s s = 804/50.25 = 16 tons of sugar The cost is found by plugging this value into either side of the original equation; it is $6904.
Answer:
28
Step-by-step explanation:
it is missing where ?
based on the answer options I guess it is missing between 20 and 36.
if that is true, then the answer is 28.
the difference between 36 and 44 is 8.
the difference between 20 and 36 is 16.
the right answer should cut the interval of 16 into 2 parts (first logical approach to cut it in 2 halves of 8) and be related to the next interval between 36 and 44 (8).
the solution covering both considerations is the middle of the large interval = 20 + 8 = 28.
