Answer:
Option C) 88
Step-by-step explanation:
We are given the following in the question:
Unit cost of sweatpants = $7
Unit cost of jackets = $14
Let x be the number of sweatpants sold and y be the number of jackets sold.
Customers bought 8 times as many sweatpants as jackets
Then, we can write,
[tex]x = 8y[/tex]
Total sales = $6,160
[tex]7x + 14y = 6160[/tex]
Substituting the values, we get,
[tex]7(8y) + 14y = 6160\\70y = 6160\\y = 88\\x = 704[/tex]
Thus, 88 jackets were sold.
Option C) 88
