So here is the answer to the given problem above. If Carly earns a weekly salary of $720 and aside from that, she gets a commission of 4%, this will be her gross pay if she sold $3250 worth of products. So 3240 multiplied by 0.04 and we get 129.6. So 720 plus 129.6 is $849.6 or $850. The answer would be the first option. Hope this helps.
