Arectangular field is three times as long as it is wide. if the perimeter of the field is 600 feet, what are the dimensions of the field?

Length (L): 3w

width (w): w

Perimeter (P) = 2L + 2w

600 = 2(3w) + 2(w)

600 = 6w + 2w

600 = 8w

75 = w

Length (L): 3w   = 3(75)   = 225

Length=225 feet, width=75 feet

A +B = 181

A=181-B

4.70A+5.90B= 967.10

4.70(181-B) +5.90B =967.10

850.70-4.70B+5.90B=967.10

850.70+1.2B =967.10

1.2B=116.40

B =116.40/1.2 = 97

A=181-97 = 84 pounds of type A coffee
