After considering the offer employer ask for different payment this has the same starting salary of 15000 but with the fixed annual pay rise $d.
find d if the total amount paid over 10 years (217500) is to be the same under the two schemes 67500


My answer is 15000*10 + 67500 *10 = 217500


The answer the end of the mei book is 1496

can someone help explaining this

thanks

15+d
15+2d
15+3d
...
15+9d
