Question 1105796
Let the number of scarves the student would have to knit and sell be x.
The student has two fixed costs, the booth and the needles for a total of 160+16= 176
And one variable cost, the yarn = 4x (four times the number of scarves)
------------------------------------------------
(15-4)x = 176
11x = 176
x = 16 this is the number of scarves the student has to knit and sell in order to break even.
