Answer:
Step-by-step explanation:
5r + 2b = 14 (5 lbs of oranges and 2 lbs of bananas = $14)
3r + 6b = 18 (3 lbs of oranges and 6 lbs of bananas = $18)
Let's use the elimination method. Multiply the first equation by -3:
-15r - 6b = -42
3r + 6b = 18
-----------------
12r = 24
Divide by 12:
r = 2

The mean is calculated by dividing the total sum of all the numbers, by the number of numbers. or in this case...
Mean=(total score)/(number of categories)
plug in the data that we know
7.25=(total score)/(8)
multiply both sides by 8
58=(total score)
Answer=58
