3.75X10^5 That seems to be the answer. You could type that in your calculator to see what you get.
Hi there! So, the simple interest is 7.5% annually. Let’s multiply by initial amount by the interest rate. 5,000 * 7.5% is 375. You earn $375 in interest annually. The difference of 6,500 and 5,000 is 1,500. Let’s divide by 375 to see how many times it goes into 1,500. 1,500/375 is 4. It will take 4 years for the balance of the account to be $6,500.
Answer: second option
Step-by-step explanation:
Direct variation equation has the following form:

Where "k" is the constant of variation.
In direct variation when the variable "x" increases, the variable "y" increases in proportion to "x" and when the variable "x" decreases, the variable "y" decreases in proportion to "x".
You can observe in the table that when "x" increases, "y" increases, therefore it is a Direct variation.
I think it is 1.5 because if u ➗ it will give u 1.5
