B. 3 bananas and 2 apples
C. 1 banana and 2 apples
D. 1 banana and 3 apples
E. 5 bananas and 2 apples
F. 5 bananas and 1 apple
The combinations of bananas and apples that Elena could buy for exactly $3.50 would be (B) as 3 bananas=1.50 and 2 apples=2.00, therefore the total is $3.50.
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Let the cost of one apple be 'x' and the cost of one banana be 'y'. Then the cost of apple and bananas is given by the equation:
0.50 x + 1.00y = 3.50
The combinations of bananas and apples that Elena could buy for exactly
$3.50 would be;
(B) as 3 bananas=1.50 and 2 apples=2.00,
Therefore the total is $3.50.
