Answer:
= -
Step-by-step explanation:
Differentiate using the power rule
(a ) = na
Given
y = = 3 , then
= - = -
Answer:
x + y < 20
5x + 10y ≥ 100
Step-by-step explanation:
The ski club wants at least $100
Student pays $5
Chaperone pays $10
Maximum number of seats = 20
Assumption:
Assumed number of students = x
Assumed number of chaperone = y
Equation:
Maximum number of seats = 20
⇒ x + y < 20
The club wants $100
⇒ 5x + 10y ≥ 100
The numerator is 5 (and the denominator is 10).
