Ali's solution is incorrect.

Ali had to add both the terms and should get 10y answer, and not multiply both terms and get answer 9y^2 which is wrong.

Step-by-step explanation:

Ali simplifies the expression 9y+y to 9y2. We need to identify if Ali's solution is correct or incorrect.

Ali's solution is incorrect.

Reason:

We are given the expression: 9y+y

When we add two like terms ( terms having the same variable and exponent), we add the coefficients of both like terms.

In our case 9y+y = 10y

Whereas Ali has done multiplication of both terms and not addition.

In multiplication we add the exponents of the same variables i.e 9y+y = 9y^2

So, Ali had to add both the terms and should get 10y answer, and not multiply both terms and get answer 9y^2 which is wrong.

Answer:

ali's solution is incorrect

9y+y is the same as 9y+1y

9y^2 is the same as 9y x y

9y+y simplifies to 10y.

I need help solving this problem

Use the given values in the compound interest formula to solve for time, n.

A is the final amount of money, $2800
P is the initial or starting amount $1900
i is the interest rate as a decimal 0.025
n is time in years since it annual.

2800 = 1900(1 + 0.025)^n

2800 = 1900(1.025)^n

2800/1900 = (1.025)^n

28/19 = (1.025)^n

take the natural log of both sides to solve for exponent.

ln(28/19) = ln(1.025^n)

power rule of logarithmic moves exponent

ln(28/19) = n*ln(1.025)

ln(28/19) / ln(1.025) = n

put into a calculator

15.7 years = n
