Answer:
9 pounds of deluxe
42 pounds of regular
Step-by-step explanation:
given data
Deluxe coffee mix with regular coffee = 51
mix contains deluxe coffee = 9 pounds
Deluxe coffee costs $5
regular coffee costr = $3
solution
we consider here
deluxe coffee = x lbs
regular coffee = y lbs
and
x+ y ≥ 52
and mixture contains at least 9 pounds of deluxe coffee
so x ≥ 9
and
cost equation will be
cost C = 5x + 3 y
deluxe costs more than regular
and here we want to use as possible as to minimize the cost
so least amount
x + y = 51
x = 9
y = 51 - 9
y = 42

Answer:
p is equal to 8.125
Step-by-step explanation:
Direct proportion formula : Y = kx ,k is constant
p = x = 3.2
r = y = 4
4 = k * 3.2
k = 4/3.2 = 1.25
y = 1.25x
Now, substitute x = 6.5 and find y.
y = 1.25 * 6.5 = 8.125
Hence p is equal to 8.125
