Question

Every

Answer 1

Answer: $66.7

Step-by-step explanation:

Answer:The equation for inverse proportion is calculated as xy=k.

When 20 people attend the picnic, the cost for each person was $50, then k will be= 20 × 50 = 1000

Recall that k = xy

For the second aspect of the question, x= 15, k= 1000.

k= xy

y = k/x

= 1000/15

= 66.7

If 15 people attend the picnic instead, the cost per person will be $66.7
