Answer:
Rate of change of money in Michael's account will be $20 per week.
Step-by-step explanation:
If we draw a graph for the duration of investment on x-axis and amount in the account on y-axis, ordered pairs for both the conditions will be,
After 6 weeks, amount in the account = $140
Ordered pair : (6, 140)
After 12 weeks, amount in the account = $260
Ordered pair : (12, 260)
Rate of change in hi account per week = ![\frac{\triangle y}{\triangle x}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctriangle%20y%7D%7B%5Ctriangle%20x%7D)
= ![\frac{260-140}{12-6}](https://tex.z-dn.net/?f=%5Cfrac%7B260-140%7D%7B12-6%7D)
= ![\frac{120}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B120%7D%7B6%7D)
= $20 per week
Therefore, rate of change of money in Michael's account will be $20 per week.
