How many pounds of each kind of candy (hard at $2 per pound, and soft at $4 per pound) must be mixed to
obtain 60 pounds of candy that is worth $3 per pound?

30 pounds of hard candy and 30 pouonds of soft candy

Step-by-step explanation:

$2 per pound added with $4 per pound would become $3 per pound

x pounds plus 60 - x pounds will add up to 60 pounds

(multiply the top with the bottom)

2x + 4x = 3(60)

6x = 180

x = 30

60 - 30 = 30

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
