Answer:
Bill is 25 years old and Jenny is 29 years old
Step-by-step explanation:
Systems of Equations:
J = 4 + B
J + B = 54
Substitute J into the first equation.
4 + B + B = 54
Add like terms.
4 + 2B = 54
Isolate the variable.
4 + 2B = 54
-4 -4
2B = 50
2B/2 = 50/2
B = 25 years old
Plug in B into the second equation of the system.
J + B = 54
J + 25 = 54
Isolate the variable.
J + 25 = 54
-25 -25
J = 29 years old
Check your answer. Pick whatever equation in the system and plug in your answers.
J = 4 + B
29 = 4 + 25
29 = 29

Answer:
Rate of depreciation = 27%
Step-by-step explanation:
Given:
Purchase price = $32,650
Rate in 2020 = $23,834.50
Find:
Rate of depreciation
Computation:
Depreciation = Purchase price - Rate in 2020
Depreciation = $32,650 - 23,834.50
Depreciation = $8,815.5
Rate of depreciation = [8,815.5 / 32650] 100
Rate of depreciation = 27%
