I’m sure the answer is B < 15
Assume that the number of apples is x and the number of oranges is y.
For the first given, we know that each apple costs $0.24 and each orange costs $0.8, therefore:
amount paid for apples = 0.24x and amount paid for oranges = 0.8y
we also know that the total amount spent is $12, therefore the first equation is as follows:
0.24x + 0.8y = 12
For the second given, we know that the total number of fruit bought is 20, therefore, the second equation is:
x + y = 20
You can easily graph these two functions and find a possible combination from the graph (the correct combination would be the intersection between the two lines).
The answer to this question is 1686.
Supplementary angles mean that when two angles are added together, they add up to 180.
Knowing that, subtract 78 from 180 to get the other angle measure, which is 102 degrees.
