Answer:

7 people need to work at a rate of 10 calls per hour.

Step-by-step explanation:

Indirect proportion:

   If the number of people working increases, the number of calls per hour will decrease.

Let x be the number of people working and y be the number of calls per hour.

  x₁ = 5 people ; y₁ = 14 calls per hour

x₂ = 7 people ; y₂ = ?

     By inverse product rule,

                x₁ * y₁ = x₂ * y₂

                5 * 14 = 7 * y₂

                       [tex]\sf y_2=\dfrac{5*14}{7}[/tex]

                            = 5*2

                            = 10

7 people need to work at a rate of 10 calls per hour.
