Problema Solution

Five packets of almonds cost 2m dollars. Mandy buys 3 packets of almonds. How much change does she receive if she paid with a $10 bill? Give your answer in terms of m.

Answer provided by our tutors

x = packets of almonds

 

5x = 2m dollars  =>  x = 0.40m dollars per packet

 

3 packs of almonds:  3(0.40) = 1.20m dollars

 

Pays with $10 bill:  (10 - 1.20)m = 8.80m

 

Mandy receives 8.80m in change.
