Answer:
y = 360(1.03)x
Step-by-step explanation:
F is the future worth, P is the present worth, I will be the interest rate, and n is the number of years.
The principal amount of the money = $360
Annual rate of interest = 3%
Thus, the amount after x years which is increased by 3%.
Since, this amount represented by y,
The required equation that represents the amount of money in Josiah’s account, y, after x years is,
This amount represented by y,
Therefore, the required equation that represents the amount of money in Josiah’s account, y, after x years is,
Hope this helps you!
Have a nice evening! ;)
Answer:
P = 0.5Q - 20
Step-by-step explanation:
P = kQ + c
substitute Q = 60 , P = 10 into the equation
10 = 60k + c → (1)
substitute Q = 240, P = 100 into the equation
100 = 240k + c → (2)
subtract (1) from (2) term by term to eliminate c
90 = 180k ( divide both sides by 180 )
=
= 0.5 = k
substitute k = 0.5 into (1) and solve for c
10 = 60(0.5) + c
10 = 30 + c ( subtract 30 from both sides )
- 20 = c
then
P = 0.5Q - 20
