Answer:
The jumbo pack is a better deal
Step-by-step explanation:
The better deal of two is the one that offers a lower cost per ride. Considering the two deals, the cost per unit ride for;
a jumbo pack of 50 ride tickets for $45 = $45/50
= $0.90 per ride
a medium pack of 30 ride tickets for $28.50
= $28.50/30
= $0.95
From the computations above, the medium pack (at $0.95) is more costly than the jumbo pack (at $0.90). Hence the jumbo pack is a better deal for Franco.
Answer:
![f(t) = -0.025t + 0.61](https://tex.z-dn.net/?f=f%28t%29%20%3D%20-0.025t%20%2B%200.61)
In which t is measured in decades.
Step-by-step explanation:
A linear function f(t) has the following format:
![f(t) = at + b](https://tex.z-dn.net/?f=f%28t%29%20%3D%20at%20%2B%20b)
We are given two points of the function, so we can solve a system of equations to find the values for a and b.
61% of all adults in 1971 (t = 0)
This means that ![f(0) = 0.61](https://tex.z-dn.net/?f=f%280%29%20%3D%200.61)
So
![f(t) = at + b](https://tex.z-dn.net/?f=f%28t%29%20%3D%20at%20%2B%20b)
![0.61 = a*(0) + b](https://tex.z-dn.net/?f=0.61%20%3D%20a%2A%280%29%20%2B%20b)
![b = 0.61](https://tex.z-dn.net/?f=b%20%3D%200.61)
51% in 2011 (t = 4)
This means that ![f(4) = 0.51](https://tex.z-dn.net/?f=f%284%29%20%3D%200.51)
So
![f(t) = at + 0.61](https://tex.z-dn.net/?f=f%28t%29%20%3D%20at%20%2B%200.61)
![0.51 = 4a + 0.61](https://tex.z-dn.net/?f=0.51%20%3D%204a%20%2B%200.61)
![4a = -0.10](https://tex.z-dn.net/?f=4a%20%3D%20-0.10)
![a = -0.025](https://tex.z-dn.net/?f=a%20%3D%20-0.025)
So the linear function is:
![f(t) = -0.025t + 0.61](https://tex.z-dn.net/?f=f%28t%29%20%3D%20-0.025t%20%2B%200.61)
In which t is measured in decades.
