Company B will start you at a higher salary. $ 168,000 annually, but will only guarantee a raise of $ 12,000 per year. Find the total salary that each company will pay you over ten-year period. Which company pays the greater total amount? Graph the data. \n" ); document.write( "

total salary is finding the sum of an arithmetic series where S=(n/2)(2a+(n-1)d)), a is $120000 for A and d is $24000. Sum is (5)(240000+(9*24000))=$2,280,000 .

\n" ); document.write( "Can look at intersection point at what seems to be x=4
