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!
