Question

Evelyn took a job that paid $100 the first week. She was guaranteed a raise of 2% each week. How much money will she make in all over 8 weeks? (Round your answer to the nearest cent.)

Answer 1

100*(1.02)^8 = 117.1659

                       = 117.17

Answer 2

$100 for week 1

 

100(1.02) = $102 for week 2

 

102(1.02) = $104.04 for week 3

 

104.04(1.02) = $106.12 for week 4

 

106.12(1.02) = $108.24 for week 5

 

108.24(1.02) = $110.40 for week 6

 

110.4(1.02) = $112.61 for week 7

 

112.61(1.02) = $114.86 for week 8

 

114.86 + 112.61 + 110.4 + 108.24 + 106.12 + 104.04 + 102 + 100 = your answer
