.

Step-by-step explanation:    

Let 'a' be the number of pounds of apples and 'b' the number of pounds of bananas.

We have been given that Lena is buying $12 worth of fruit to bring as a class snack. Apples are $1.40 per pound and bananas are $1.25 per pound.

We know that standard form of equation is in format , where A, B and C are integers.

Since the cost of per pound of apples is $1.40, so cost of 'a' pounds of apples would be .

Since the cost of per pound of bananas is $1.25, so cost of 'b' pounds of apples would be .

We are also told that the fruits are worth $12, we can represent this information in an equation as:

Therefore, the equation represents the given scenario in standard form of equation.
