PLEASE HELP QUICK 100 POINTS

Amanda is putting money into a checking account. Let y represent the total amount of money in the account (in dollars). Let x represent the number of weeks
Amanda has been adding money. Suppose that x and y are related by the equation y=550+20x.
Answer the questions below.
Note that a change can be an increase or a decrease.
For an increase, use a positive number. For a decrease, use a negative number.

Answer 1

Change per week: $20

Starting amount of money: $550

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.
