Answer:
A. $1.10 B. $6.60
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
