Answer:
Change per week: $20
Starting amount of money: $550
Step-by-step explanation:
<u>Given equation</u>:
![y=550+20x](https://tex.z-dn.net/?f=y%3D550%2B20x)
where:
- x = number of weeks
- y = total account balance
<u>Change per week</u>
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.
<u>Initial Balance</u>
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](https://tex.z-dn.net/?f=%5Cimplies%20y%3D550%2B20%280%29%3D550)
Therefore, the starting amount of money in the account is $550.
You first separate the triangle from the rectangle. Then multiply one side be one side.
