Ena 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. let a be the number of pounds of apples and b the number of pounds of bananas. write an equation in standard form to model the scenario.

$12 = $1.40a + $1.25b

think this is it... Hope this helps... :)

1.40a + 1.25b = 12

1.40 is the price of apples, a is the amount of apples,
1.25 is the price of bananas, b is the amount of bananas.

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
