Final answer:
Gwen spent $609 at Target on Black Friday, after calculating the amounts spent at Best Buy and Kohls from her total expenditure of $783.
Step-by-step explanation:
To solve the problem regarding the amount spent at Target by Gwen on Black Friday, we must first calculate the money spent at Best Buy. Since Gwen spent a total of $783 and 1/9 of that was spent at Best Buy, we perform the following calculation:
- Amount spent at Best Buy: (1/9) × $783 = $87.
- Money left after spending at Best Buy: $783 - $87 = $696.
- Next, she spent 1/8 of the remaining amount at Kohls, so we calculate that amount: (1/8) × $696 = $87.
- Money left after spending at Kohls: $696 - $87 = $609.
- The rest of the money, which is $609, was spent at Target.
Therefore, Gwen spent $609 at Target.
