Deandre went to the pet store and could buy two different brands of dog food. Brand A costs $35 for seven pounds. Brand B costs $40 for 7.5 pounds. Which brand of dog food is the better deal? Explain your choice mathematically.

Suredude why not right

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0 

Google it i would but this is hard the answer is on google trust me
