Chem deposited $115.00 in a savings account. each week thereafter, he
deposits $35.00 into the account.
a. write a function to represent the total amount chem has deposited for any particular
number of weeks after his initial deposit.
b. how much has chem deposited 30 weeks after his initial deposit?

Part a)

Part b)

Step-by-step explanation:

Part a)

Let

x -----> the number of weeks

y ----> the total amount Chem has deposited in a saving account

we know that

The equation of a line in slope intercept form is

where

m is the rate or slope of the linear equation

b is the y-intercept of the linear equation or initial value (value of y when the value of x is equal to zero)

In this problem we have that

The rate or slope is equal to

-----> amount deposited by Chem each week

The y-intercept or initial value is

----> amount deposited originally in the saving account

substitute the values

Part b) How much has Chem deposited 30 weeks after his initial deposit?

For x=30 weeks

substitute in the equation

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
