Stacie is choosing between two careers. working for company a, stacie will make $45,000 the first year and will receive an additional $1,500 per year for each year worked. working for company b, stacie will make $42,000 the first year, and she will receive an additional $1,800 per year for each year worked. the expressions representing each company’s total pay over 30 years are shown below. how much more will company b pay over 30 years? $12,000 $40,500 $49,200 $49,500

The expression in company B represents that is is in arithmetic progression where first term is 42000 and common difference is 1800 . So we have to use the formula of sum of n terms which is

Where a is the first term, n is the nth term, d is the common difference

On substituting there values,we will get

= 15(84000+52200) = 15*136200 =2043000

And for company A, it is

Difference between them =2043000-2002500= 40500

So the correct option is the second option .
