The associative property states that you can add or multiply regardless of how the numbers are grouped. By"grouped" we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis

Jeo is comparing the price of different boxes of cereal. One box has 16 oz. and costs $3.50. Another costs $3.89 for a 24 oz. bo

velikii [3]

Answer:

The difference in cost, in dollars, per ounce between the two boxes of cereal is $0.06.

Step-by-step explanation:

☆Let's solve using proportion.

☆One box:

$\frac{16 \: oz.}{3.50 \: dollars} = \frac{1 \: oz.}{x} \\ \\ \frac{3.50}{16} = \frac{16x}{16 } \\ \\ 0.22 = x$

☆Another box:

$\frac{24 \: oz.}{3.89 \: dollars} = \frac{1 \: oz.}{x } \\ \\ \frac{3.89}{24} = \frac{24x}{24} \\ \\ x = 0.16$

☆All we need to do is subtract: $0.22 - 0.16 = 0.06$

☆The difference in cost, in dollars, per ounce between the two boxes of cereal is $0.06.
