Danielle earns a 7.75% commission on everything she sales at the electronic store where she works. She also earns a base salary
Andrew [12]

The first thing thing you must do is create an equation for this problem. Remembering that 7.75% = 0.0775

($4,100 × 0.0775 + $4,100 ) + $600

Now, all you have to do is solve it. You will first have to start with the numbers in the parenthesis using the order of operation (PEMDAS).

P = Parenthesis

E = Exponent

M = Multiplication

D = Division

A = Addition

S = Subrtaction

$4,100 × 0.0775 + $4,100 ) + $600

$4,417. 75 + $4,100 + $600

$4,417. 75 + $600 = $5,017.75

Danielle made $5,017. 17 last week.

I hope this helps! :)
