Job A sales offer a base salary of $1,000 per week plus 3% commission on sales above $3000. Job B sales offers a base salary of $1,100 per week plus 2.5% commission on all sales above $3000. The total sales for the week equal $25,000. How much more does Job A pay than Job B?

First, let's calculate the total commission for each job based on the total sales.

For Job A:
Commission for sales above $3000 = 3% of ($25,000 - $3,000) = 3% of $22,000 = $660

Total earnings for Job A = Base salary + Commission = $1,000 + $660 = $1,660

For Job B:
Commission for all sales above $3000 = 2.5% of $25,000 = $625

Total earnings for Job B = Base salary + Commission = $1,100 + $625 = $1,725

Now, let's find the difference in pay between the two jobs:
Difference = Total earnings for Job A - Total earnings for Job B
Difference = $1,660 - $1,725 = $65

Therefore, Job A pays $65 more than Job B.
