D + q = 40
.10d +.25q= $7.75

d +q = 40
d =40-q
.10(40-q) +.25q= $7.75
4 - .10q + .25q =7.75
4 +.15q =7.75
4-4 +.15q =7.75-4
.15q= 3.75
.15q/.15 = 3.75/.15
q = 25

d =40-25
d = 15

Check
.10(15) +.25(25)= $7.75
1.5+6.25=7.75
7.75=7.75

Nezavi [6.7K]

Answer:

The house will be worth $184,699.6847 in 6 months.

Step-by-step explanation:

Since the cost of the houses is dropping by 2.5 % per month, then it is decreasing exponentially and can be modeled by the following formula:

$cost(x) = 215000*(1 - \frac{2.5}{100})^t\\cost(x) = 215000*(1 - 0.025)^t\\cost(x) = 215000*(0.975)^t\\$

After 6 months:

$cost(6) = 215000*(0.975)^6\\cost(6) = 184699.6847$

The house will be worth $184,699.6847 in 6 months.
