Well, if the integer is negative it would be positive, if it was positive it would be negative.
Negative x Positive = Negative
Negative x Negative = Positive

Answer:
192 pounds of $2.5 brand
288 pounds of $2.8 brand
Step-by-step explanation:
From the information we can write an expression that relates the two brands the total pounds of coffee the grocer wants to see. Let x be pounds of the coffee brand 1 and y be pounds of the coffee brand 2.Equation 1:
We know that the price of will be equation 2:
Two equations and two unknowns we can solve for x and y:
Substitute into the second equation:
Therefore he uses 288 pounds of brand two at $2.80 and 480-288=192 pounds of brand 1 at $2.50
