Aleka and helene both opened savings accounts that earn 2.5% interest a year. aleka puts $2,500 into her account. helene put $1,500 into her account and also saves $200 cash a year. x = number of years aleka: f(x) = 2500(1.025)x helene: g(x) = 1500(1.025)x + 200x which function represents the difference, h(x) = f(x) – g(x), between the value of aleka’s and helene’s total savings after x years?

.

Step-by-step explanation:

We are given function f for Aleka's amount

And function for Helene's amount

.

Now, we need to find the difference of the functions h(x) = f(x)-g(x).

Subtracting f(x) and g(x), function, we get

Distributing minus sign over second parenthesis, we get

Subtracting , we get 1000.

Therefore, .

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

this is not the answer this is just a question. is this middle school math?
