The exponential graph is shown below.
The initial value when the time is zero is 70000. An initial value is normally shown as the point where the graph crosses the y-axis.
If the initial value was to be 50000, the curve would have crossed the y-axis at 50000
The correct answer is the first statement
3,000. You take 15,000 and multiply by .4 to get how much she spent on rent (6,000). They you subtract the rent money from her total pay to get her money that she spent on living expenses, clothes and entertainment in total (9,000). Since she spent her money in six parts (3+2+1), you divide 9,000 by 6 to get 1,500 to get each part. Since for entertainment she has two parts you multiply 1,500 by 2 to get 3,000.
3/4 is longer than 2/15 by 37/60
