y=x+1.75

substitute for y in equation 2.

4x-2(x+1.75)=4

4x-2x-3.5=4

2x=7.5

x=3.75

y=3.75+1.75

y=5.5

Suppose you borrow 13,000 for four years at 7% toward the purchase of a car.

dangina [55]

Amount borrowed, P = 13000
Interest, i = 0.07/12 per month
number of periods (months), n = 4*12 = 48

Monthly payment,
$A=\frac{P(i*(1+i)^n)}{(1+i)^n-1}$
$=\frac{13000(.07/12*(1+.07/12)^{48}}{(1+.07/12)^{48}-1}$
=311.30 (to the nearest cent)
