Respuesta :

3 1/2 is the same thing as 3.5 (I find it's easier to work with decimals rather than with fractions)!

You need to do a cross product in order to find your answer:

1 gallon of milk = 0.58$

3.5 gallons of milk = X$


(0.58 × 3.5) ÷ 1 = X$

2.03 ÷ 1 = X$

2.03 = X$


Your answer is : 3 1/2 gallons of milk would cost $2.03
