x = number of pounds of type A coffee

y = number of pounds of type B coffee

Keisha made 151 pounds of the blend, so x+y = 151 which solves to y = -x+151

The second equation is 5.65*x + 4.55*y = 791.55

since 5.65*x represents the total cost of just type A alone and 4.55*y represents all of type B only. The two subtotals combine to a grand total of 5.65*x + 4.55*y which is set equal to the final cost 791.55

5.65*x + 4.55*y = 791.55

5.65*x + 4.55*(y) = 791.55

5.65*x + 4.55*(-x+151) = 791.55 <--- replace y with -x+151

5.65*x - 4.55x + 687.05  = 791.55

1.10x + 687.05  = 791.55

1.10x+687.05-687.05=791.55-687.05 <- subtract 687.05 from both sides

1.10x = 104.5

1.10x/1.10 = 104.5/1.10 <--- divide both sides by 1.10

x = 95

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
