A saleswomen sells a dried fruit mixture for $5.7 per pound and nuts for $14.55 per pound. She wants to blend the two to get a 1 0 pound mixture that she will sell for $9.24 per pound. How much should she use? to get a 10 pound mixture she should use __ lb of fruit mixture and __ lb of nuts.
1 answer:
Let the fruit mixture of $5.7 per pound be for x pounds. The nut of $14.55 per pound would then be: (10 -x). Since the total blend of both = 10 pounds, selling for $9.24 per pound. cost of 1st type + cost of second type = Total cost of blend mixture 5.7*x + 14.55*(10 - x) = 9.24*10 5.7x + 145.5 - 14.55x = 92.4 5.7x - 14.55x = 92.4 - 145.5 -8.85x = -53.1 x = -53.1/-8.85 x = 6 The other will be (10 -x) = 10 - 6 = 4. She should use 6 lb of fruit mixture and 4 lb of nuts.

Answer:
y-1=2(x+4) or y=2x+9
Step-by-step explanation:
y - 3 = 2(x + 7)
y=mx+b
m=2
(x1,y1) -> (-4, 1)
(y−y1)=m(x−x1)
plug in
y-1=2(x+4)
y-1=2x+8
y=2x+9
test:
(1)=2(-4)+9
1=-8+9
1=1
