posledela

Answer:

  • 1 pounds of apples = \1·25
  • 1 pounds of cheese = \7
  • 1 pounds of coffee beans = \5·5
  • 1 pounds of fudge = \9
  • 1 pounds of pumpkin = \0·88

Step-by-step explanation:

Unit Rate is the ratio between two different quantities with different units

The ratio of cost per items is

=  \frac{dollars}{pounds}

4 pounds of apples  = \5

4 pounds = \5

Divided 4 both the side

1 pounds of apples = \1·25

\frac{1}{2} pounds of cheese = \3·50

\frac{1}{2} pounds = \3·50

Divided \frac{1}{2} both the side

1 pounds of cheese = \7

\frac{3}{2} pounds of coffe beans = \8·25

\frac{3}{2} pounds = \8·25

Divided \frac{3}{2} both the side

1 pounds of coffee beans = \5·5

\frac{3}{4} pounds of fudge = \6·75

\frac{3}{4} pounds = \6·75

Divided \frac{3}{4} both the side

1 pounds of fudge = \9

\frac{25}{4} pounds of pumpkin is = \5·50

\frac{25}{4} pounds = \5·50

Divided \frac{25}{4} both the side

1 pounds of pumpkin = \0·88
