Ric made two investments: investment \text{q}q has a value of \$500$500 at the end of the first year and increases by \$45$45 per year. investment \text{r}r has a value of \$400$400 at the end of the first year and increases by 10\%10% per year. eric checks the value of his investments once a year, at the end of the year. what is the first year in which eric sees that investment \text{r}r's value exceeded investment \text{q}q's value?

10th year

Step-by-step explanation:

Ric made two investments.

Investment Q

Amount = $500 at end of the year

Increase $45 per year.

Value of investment after x year

we take time (x-1) because investment was end of first year.

Investment R

Amount = $400 at end of the year

Increase 10% per year.

Value of investment after x year

we take time (x-1) because investment was end of first year.

Eric checks the value of his investments once a year, at the end of the year.

Eric sees that investment R's value exceeded investment Q's value

Investment R > Investment Q

Using graphing calculator

Hence, In 10th year Investment R could be greater than Investment Q
