The next larger ten is . . . . . . 50 .
The next smaller ten is . . . . . . 40 .
. . . . . . 49 is closer to . . . . . . 50 than it is to . . . . . . 40 .
So the nearest ten is . . . . . . 50 .
Lets use the letter C to represent cats and D to represent dogs.
A) 2.35c + 5.50d = 89.50
For B, they give you numbers to plug into your equation.
c = 8
d= 14
B) 2.35(8) + 5.50(14) = 89.50
18.80 + 77.00 = 95.80
So what Pat said is incorrect because that would mean they spent more than 89.50.
Hope this helps! :)

Answer:
(a)$5805.21
(b)Least Expensive Mortgage =$120640.59
Most Expensive Mortgage =$152032.77
Step-by-step explanation:
The future value of an ordinary annuity with deposits P made regularly k times each year for n years, with interest compounded times k per year at an annual rate r, is given as:
![F.V.=\dfrac{P[(1+i)^{kn}-1]}{i}](https://tex.z-dn.net/?f=F.V.%3D%5Cdfrac%7BP%5B%281%2Bi%29%5E%7Bkn%7D-1%5D%7D%7Bi%7D)
The Pirerra's Monthly Payments=$140
Annual Rate =9.5%
Therefore: Monthly Rate=0.095/12
Years, n=3
Period, k=12
![F.V.=\dfrac{140[(1+\frac{0.095}{12} )^{3*12}-1]}{\frac{0.095}{12} }=\$5805.21](https://tex.z-dn.net/?f=F.V.%3D%5Cdfrac%7B140%5B%281%2B%5Cfrac%7B0.095%7D%7B12%7D%20%29%5E%7B3%2A12%7D-1%5D%7D%7B%5Cfrac%7B0.095%7D%7B12%7D%20%7D%3D%5C%245805.21)
(b)For the Johnsons, Present value of Mortgage is derived using the formula:
![\Text{Present Lump Sum}, A_0=\dfrac{P[1-(1+i)^{-kt}]}{\frac{r}{k} }](https://tex.z-dn.net/?f=%5CText%7BPresent%20Lump%20Sum%7D%2C%20A_0%3D%5Cdfrac%7BP%5B1-%281%2Bi%29%5E%7B-kt%7D%5D%7D%7B%5Cfrac%7Br%7D%7Bk%7D%20%7D)
At $1000 Monthly payment
![\Text{Present Lump Sum}, A_0=\dfrac{1000[1-(1+\frac{0.08}{12} )^{-12*15}]}{\frac{0.08}{12} }=\$104640.59](https://tex.z-dn.net/?f=%5CText%7BPresent%20Lump%20Sum%7D%2C%20A_0%3D%5Cdfrac%7B1000%5B1-%281%2B%5Cfrac%7B0.08%7D%7B12%7D%20%29%5E%7B-12%2A15%7D%5D%7D%7B%5Cfrac%7B0.08%7D%7B12%7D%20%7D%3D%5C%24104640.59)
Adding a down payment of $16000
- Least Expensive Mortgage = 104640.59+16000=$120640.59
At $1300 Monthly Payment
![\Text{Present Lump Sum}, A_0=\dfrac{1300[1-(1+\frac{0.08}{12} )^{-12*15}]}{\frac{0.08}{12} }=\$136032.77](https://tex.z-dn.net/?f=%5CText%7BPresent%20Lump%20Sum%7D%2C%20A_0%3D%5Cdfrac%7B1300%5B1-%281%2B%5Cfrac%7B0.08%7D%7B12%7D%20%29%5E%7B-12%2A15%7D%5D%7D%7B%5Cfrac%7B0.08%7D%7B12%7D%20%7D%3D%5C%24136032.77)
Adding a down payment of $16000
- Most Expensive Mortgage = 136032.77+16000=$152032.77
If events A and B are independent,
For mutually exclusive then p(A or B) = p(A) + p(B).
For not mutually exclusive then p(A or B) = p(A) + p(B) - p(A and B)
And: p(A and B) = p(A) * p(B)
Given: <span>p(A) = 0.22 and p(B) = 0.24.
</span>
<span>∴ p(A and B) = p(A) * p(B) = 0.22*0.24 = 0.0528
</span>
If A and B are mutually exclusive
∴ p(A or B) = p(A) + p(B) = 0.22 + 0.24 = 0.46
If A and B are not mutually exclusive
∴ p(A or B) = p(A) + p(B) - p(A and B) = 0.22 + 0.24 - <span>0.0528 = 0.4072
</span>
=============================================
note: Two events are mutually exclusive if it is not possible for both of them to occur, which mean the occurrence of one event "excludes" the possibility of the other event.
