2/9 = d / 27
cross multiply
(9)(d) = (27)(2)
9d = 54
d = 54/9
d = 6 <==
When an exponent is outside the parenthesis, you multiply them.
13*19=247
“C” 2^247 is the answer.
I hope this helps!

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
