2) Joel took out an 80/20 mortgage to buy a house costing $586,000. The first (80%) mortgage has an interest rate of 3.65%, and the second (20%) mortgage has an interest rate of 6.9%. Both are 30-year fixed-rate mortgages.
a) What is the amount of Joel's first mortgage?
b) What is the amount of Joel's second mortgage?
c) What is the monthly payment for Joel's first mortgage?
d) What is the monthly payment for Joel's second mortgage?
e) What is Joel's total monthly payment for his 80/20 mortgage?
f) What is the actual interest rate for Joel's 80/20 mortgage?

3, 12, 48, 384, 1536, 6144, 24576, 98304

step-by-step explanation:

just keep timing it by 4.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

definitely a. the others have almost all data points on one side of the line.
