A. $1.1

B. $6.6

Step-by-step explanation:

Let x represent the number of boxes.

We have been given that Thomas buys a certain brand of cereal that costs $8 per box. So the cost of x boxes would be .

We are also told that Luke changes to a super-saving brand of the same size. The equation shows the price, y, as the number of boxes, x, for the new brand.

A. The price of original box is $8 and price of each box of the super-saving brand is $6.9.

To solve part A, we need to subtract price of one box of the super-saving brand from price of a box of Thomas’ original brand as:

Therefore, the price of a box of Thomas’ original brand of cereal is 1.1 dollars more than the price of a box of the super-saving brand.

B. We can conclude from the findings of part A that $1.1 is saved per box with the change in cereal brand.

Since he buys 6 cereal boxes each month, so amount saved per month would be 6 times $1.1

Therefore, he saves $6.6 each month with the change in cereal brand.
