If 2 1/4 pounds of bananas cost $1.89, what is the cost per pound?

Svetach [21]

Answer:

The cost per pound of bananas is $0.84.

Step-by-step explanation:

The question asks to use the given information to set up a proportion and solve for the missing variable. In this case, we know that the cost of 2 1/4 (or 2.25) bananas is $1.89. Since they are asking for cost per pound, we can set up a ratio (fraction):

$\frac{1.89}{2.25}=\frac{cost}{pounds}$

Since the cost of bananas is the same regardless of the number of pounds, we can set up a proportion to find the cost for just one (1) pound:

$\frac{1.89}{2.25}=\frac{x}{1}$ Where 'x' is the cost.

Using cross-multiplication and division we get: 2.25x = 1.89. Next, we use inverse operations to divide both sides by 2.25: 2.25x/2.25 = 1.89/2.25. Solve: x = 0.84 or $0.84 per pound.
