Question

A company sells boxes of bracelets (b) for $30 and boxes of necklaces (n) for $50. They make batches of bracelets that fill 5 boxes and batches of necklaces that fill 7 boxes. The company only has 48 boxes. Which system of equations helps the company plan to make $320?
a
b = 48 − n
5b + 7n = 48

b
b = 48 − n
30b + 50n = 320

c
5b = 48 − 7n
30b + 50n = 320

d
5b = 48 − 7n
30b − 50n = 320

Answer 1

The variable b is boxes of bracelets ($30)
The variable n is boxes of necklaces ($50)

the amount of money amassed needs to equal 320 dollars

30b + 50n = 320

hopefully you understand how I got that

They make batches of bracelets that fill 5 boxes and batches of necklaces that fill 7 boxes. The company only has 48 boxes.

5b + 7n = 48 -> 5b = 48 - 7n

hopefully you understand how I got that too

if you don't, please reply!
