The cost of 4 bananas and 4 oranges is $36.
The cost of 4 bananas and 4 oranges is $36. The cost of 2 bananas and 5 oranges is $33. What is the cost of 1 orange?
Answer/Solution
5
Steps/Work
Let the cost of 1 banana = x, let the cost of 1 orange = y
4x + 4y = 36
x = (36 - 4y)/4
x = 9 - y
Again,
2x + 5y = 33
2(9 - y) + 5y = 33
18 - 2y + 5y = 33
3y = 15
y = 5
Answer: B
4x + 4y = 36
x = (36 - 4y)/4
x = 9 - y
Again,
2x + 5y = 33
2(9 - y) + 5y = 33
18 - 2y + 5y = 33
3y = 15
y = 5
Answer: B
