Studdy Solution

STEP 1

Assumptions1. The initial annual salary is 43,000.Theannualsalaryraiseis43,000. The annual salary raise is ,0003. The salary raise is given at the end of each year4. The raise is added to the previous year's salary to form the new salary for the next year

STEP 2

First, we need to find the formula for the salary after tt years. Since the salary increases by a constant amount each year, we can use the formula for an arithmetic sequence.
Salaryt=Initialsalary+(t1)timesAnnualraiseSalary_t = Initial\, salary + (t-1) \\times Annual\, raise

STEP 3

Now, plug in the given values for the initial salary and annual raise to calculate the salary after7 years.
Salary7=$43,000+(71)times$2,000Salary7 = \$43,000 + (7-1) \\times \$2,000

STEP 4

implify the expression.
Salary7=$43,000+6times$2,000Salary7 = \$43,000 +6 \\times \$2,000

STEP 5

Calculate the salary after7 years.
Salary7=$43,000+$12,000=$55,000Salary7 = \$43,000 + \$12,000 = \$55,000Camden would make $55,000 as a salary after7 years working for the company.

STEP 6

Now, let's find the general formula for the salary after tt years. We can use the same formula as in2.
Salaryt=$43,000+(t1)times$2,000Salary_t = \$43,000 + (t-1) \\times \$2,000This is the formula for Camden's salary after tt years working for the company.
