If the cost increases $0.90 every three years , then the cost increases $0.30 per year. the slope will be 0.3/1 or just 0.3
A=3 so 8*3=24.......................
967.50 = 450 + 28.75p
967.50 - 450 = 28.75p
517.5 = 28.75p
18 = p
Answer:
1st option
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use (3, 8 ) , that is x = 3 when y = 8 , then
8 =
( multiply both sides by 3 )
24 = k
y =
← equation of variation
