Rebecca was comparing various sizes of cannot applesauce. A 16-02 can of one brand costs $7.78 and a 12-oz can of the same brand costs $6.86. Find the savings to thenearest cent on buying 36 ounces of applesauce in 16-02 cans compared to 12-02. cans.$8.903787$8.12$9.06None of these choices are correct

Answer 1

We first need to find the unit rates so we can know what the price of one ounce is.

For the 16-oz can of applesauce, we will divide 7.78 by 16.

$\frac{7.78}{16}=0.49$

Therefore, to find the price of 36 ounces of this specific can of applesauce, we will multiply this unit rate by 36.

$36\times0.49=17.64$

We can use the same method for the second can, except we divide 6.86 by 12.

$\frac{6.86}{12}=0.57$

Then, we multiply this by 36.

$36\times0.57=20.52$

Now, we need to subtract the two to find the price difference.

$20.52-17.64=2.88$

You would save $2.88 by buying a 16-ounce can in comparison to buying a 12-ounce can. This means that Choice E, "None of these choices are correct," is correct.
