Answer:
16 months
Step-by-step explanation:
Look at the chart on the left and look at what number of months is closest to 15,000. 16 is at 15,034
To solve mathematically:
y is the balance that his account would have. You want to find the amount of months it will take before it becomes $15,000, so 15000 is your y value
15,000= - 440.91x+22,060.7
-7,060.7= - 440.91x Subtract 22,060.7 from both sides
16.0139=x Divide both sides by - 440.91
