Ответ:
1 bracelet requires 313 in. of wire
The total length of wire = 2813.
Let x = the number of necklaces made.
Let y = the number of bracelets made.
The total amount of wire used is 2813 in., therefore
619x + 313y = 2813
y = (2813 -619x)/313
y = 8.9872 - 1.9976x
Create a table of x versus y.
x: 0 1 2 3 4
y: 9 7 5 3 1
(0,9), (1,7), (2,5), (3,3), (4,1)
