Semmy [17]

Greta starts with $100 in her savings account

She adds $50 each week

Balance after week 1 = 100 + 50 = 150

Part A

Unit rate of change here is = $\frac{\text{Balance after week 1 - Initial balance}}{\text{Initial balance}} * 100$

⇒ Unit rate of change here is = $\frac{\text{150 - 100}}{\text{100}} * 100$

⇒ Unit rate of change here is = 50%

Part B

Equation to calculate the amount of money Greta will have after any number of weeks = ?

Money after 'x' number of weeks = $\text{Initial Deposit + x * Weekly Deposit}$

⇒ Money after 'x' number of weeks = $\text{100 + x * 50}$

Part C

Money Greta will have after 1 year= ?

In a year there are 52 weeks

So, putting x = 52 in the solution of Part B

⇒ Money after 52 weeks = $\text{100 + 52 * 50}$

⇒ Money after 52 weeks = $\text{100 + 2,600}$

⇒ Money after 52 weeks = 2,700
