Answer:
Last week her sales were $4500.
Step-by-step explanation:
Given:
Danielle earns a 7.25% commission on everything she sells at the electronics store where she works.
She also earns a base salary of $750 per week.
Her total earnings for the week were $1,076.25.
Now, to find her sales last week.
Let the sales of last week be [tex]x.[/tex]
Base salary = $750.
Total earnings = $1076.25.
So, we deduct the base salary from the total earnings first:
[tex]1076.25-750[/tex]
[tex]=326.25.[/tex]
Thus, the rest of the earnings is $326.25 which is the 7.25% commission on sales.
Now, to get the sales of last week we put an equation:
[tex]7.25\%\ of\ x=326.25[/tex]
[tex]\frac{7.25}{100} \times x=326.25[/tex]
[tex]\frac{7.25x}{100} =326.25[/tex]
Multiplying both sides by 100 we get:
[tex]7.25x=32625[/tex]
Dividing both sides by 7.25 we get:
[tex]x=4500.[/tex]
The sales of last week = $4500.
Therefore, last week her sales were $4500.
