In 1 hour samantha can make 6 beaded bracelets. in 3 hours she can make 18 bracelets. how many can she make in 4 fours? provide explanation! if you don't know the answer, then don't reply to this. a. 21 b. 24 c. 27 d. 30

Basically Samantha makes six bracelets per hour, so:
After 1 hour she makes 6
After 2 hours she makes 12
After 3 hours she makes 18
After 4 hours she makes 24, therefor the answer is B

This can also be modelled by the equation B = 6t, where B is the number of bracelets and t is the number of hours, so:
B = 6(4) = 24
