Answer:
$1,220,200
Step-by-step explanation:
The total of Mary's payments is ...
$3695.20/mo × 30 yr × 12 mo/yr = $1,330,200
The difference between this repayment amount and the value of her loan is the interest she pays:
$1,330,200 -110,000 = $1,220,200 . . . total interest paid
_____
Mary's effective interest rate is about 40.31% per year--exorbitant by any standard.
Answer:
The y-coordinate of their intersection point is 3
That is y=3
Step-by-step explanation:
Given two lines are y=6x+15 and y=mx+4
Given that the two lines intersect at x=-2
To find the y coordinate of their intersection point :
Equating the two lines
6x+15=mx+4
6x+15-mx-4=0
6x-mx+11=0
(6-m)x+11=0
At x=-2 (6-m)x+11=0
(6-m)(-2)+11=0
(6-m)(-2)=-11
![6-m=\frac{11}{2}](https://tex.z-dn.net/?f=6-m%3D%5Cfrac%7B11%7D%7B2%7D)
![-m=\frac{11}{2}-6](https://tex.z-dn.net/?f=-m%3D%5Cfrac%7B11%7D%7B2%7D-6)
![-m=\frac{11-12}{2}](https://tex.z-dn.net/?f=-m%3D%5Cfrac%7B11-12%7D%7B2%7D)
![-m=\frac{-1}{2}](https://tex.z-dn.net/?f=-m%3D%5Cfrac%7B-1%7D%7B2%7D)
![m=\frac{1}{2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B1%7D%7B2%7D)
Substitute the value
in y=mx+4 we get
![y=\frac{1}{2}x+4](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B2%7Dx%2B4)
At x=-2 ![y=\frac{1}{2}(-2)+4](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B2%7D%28-2%29%2B4)
![=-1+4](https://tex.z-dn.net/?f=%3D-1%2B4)
![=3](https://tex.z-dn.net/?f=%3D3)
Therefore y=3
Therefore the y-coordinate of their intersection point is 3
The answer is B, you will need at least 6 spring roll wrapper packages.
The way you get the answer is by turning the word problem into an expression. You can make this into the fraction (17*6+15*3)/(25). 17 is the number of adults and you multiply this by how many spring rolls Jill wants to give each adult, which is 6, you can do the same for the children. Next the denominator is 25 which represents the amount of spring roll wrappers per each package. When you simplify the answer comes around to 5.88, but since you cant buy 88% of a spring role wrap package you have to buy another whole one, which makes the answer six.
Last one and first. You can find out why by isolating the cube root and cubing both sides.
