Danielle earns a 7.25% commission on everything she sells at the electronic store where she works,.she also earns a base salary of $750 per week .how mcuh did she earn last week if she sold 4,000 in electronics merchandice?

29,750 is the answer for the problem

First, let's create an equation for this problem. Remember 7.25% = 0.0725
 ($4,000 × 0.0725 + $4,000 ) + $750

Now, all you have to do is solve it. You would start in the parenthesis using the order of operation (PEMDAS).
($4,000 × 0.0725 + $4,000 ) + $750
$4290 + $750 = $5,040

Danielle made $5,040 last week. 

I hope this helps!
