Answer 1

Answer:

Change per week: $20

Starting amount of money: $550

Step-by-step explanation:

Given equation:

$y=550+20x$

where:

• x = number of weeks
• y = total account balance

Change per week

As the variable x represents the number of weeks, its coefficient represents the change per week in the amount of money.

Therefore, the change per week in the amount of money in the account is $20.

Initial Balance

The starting amount of money in the account (initial balance) will be the value of y when x = 0:

$\implies y=550+20(0)=550$

Therefore, the starting amount of money in the account is $550.
