Ms. Clark will make $ 34,850 in her tenth year.
What is an arithmetic progression?
An arithmetic progression, also known as an arithmetic sequence, is a set of numbers in which the difference between successive terms remains constant.
@@MATH_TOKEN_0@@ = a + (n-1)d
Let the amount she made in her 1st year = a
The increment she gets each year = d
@@MATH_TOKEN_1@@ = a + 2d
29600 = a + 2d ..(1)
@@MATH_TOKEN_2@@ = a + 6d
32600 = a + 6d ..(2)
Subtract the 1st equation from the 2nd equation:
4d = 3000
d = $750
Put the value of d in 1st equation:
a = $28100
@@MATH_TOKEN_3@@ = a + 9d
@@MATH_TOKEN_4@@ = 28100 + 9 ( 750 )
@@MATH_TOKEN_5@@ = $34850
Hence, Ms. Clark will make $ 34,850 in her tenth year.
