Answer:

x = 14

Step-by-step explanation:

We are given that A, B and C are collinear points and B is in between A and C.

The length from A to B is $3 x$ , length from B to C is $2x - 7$ and AC is $2 x + 35$ .

We are to find the value of x.

$A B + B C = A C$

$3 x + 2 x - 7 = 2 x + 3 5$

$3 x + 2 x - 2 x = 3 5 + 7$

$3 x = 4 2$

$x = \frac { 4 2 } { 3 }$

x = 14

Answer:

$1516.69 per month less

Step-by-step explanation:

The formula for the monthly payment A on a loan of principal P, annual rate r, for t years is ...

A = P(r/12)/(1 -(1 +r/12)^(-12t))

For the 18.5% loan, the monthly payment is ...

A = 150000(.185/12)/(1 -(1 +.185/12)^(-12·30)) ≈ 2321.92

For the 5% loan, the monthly payment is ...

A = 150000(.05/12)/(1 -(1 +.05/12)^-360) ≈ 805.23

The mortgage at 5% would be $1516.69 less per month.
