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:
357 minutes
Step-by-step explanation:
I subtracted 9 cents/minute from the 23 cents/minute to get 14 cents to get the difference between the two per minute charges. I then divided the monthly cost of $49.95 by .14 to get 356.79... So if you used 357 minutes in a month, the second plan would be 3 cents cheaper at $82.08 (.09 x 357= 32.13 + 49.95), vs. the first plan costing $82.11 (.23 x 357). At 356 minutes the first plan would still be cheaper.
