Answer:

A. $1.10      B. $6.60

Step-by-step explanation:

A. The equation y = 6.9x shows that the price of the new cereal is $6.90 because if x is 1 then the price is 6.9. From this we can find the difference of prices between the two cereal boxes: 8 - 6.9 = $1.10

B. The total amount of money for the original cereal is $8 × 6 = $48

The amount of money for the new cereal is $6.90 × 6 = $41.40

The money saved is: $48 - $14.40 = $6.60
