$3787.5

Step-by-step explanation:

Given data

Cost price=  $25,000

Rate of decrease= 7%

Time= 2020-2026= 26 years

Let us apply the formula

A= P(1-r)^t

substitute

A= 25000(1-0.07)^26

A=25000(0.93)^26

A= 25000*0.1515

A= $3787.5

Hence the worth will be $3787.5

Select the correct answer.
asambeis [7]

Answer:

y=3x+4

Step-by-step explanation:

The equation of the straight line that passes through (-3,-5) with slope 3 can be found using

y = mx + b

where m=3 is the slope .

We substitute the slope to get:

y = 3x + b

We substitute the point to find b.

- 5 = 3( - 3) + b \\  - 5 =  - 9 + b \\ b =  - 5 + 9 = 4

The equation of the straight line is:

y = 3x + 4
