A box of eggs and a jug of milk cost $5. Two boxes of eggs and three jugs of milk cost $13. How much is a box of eggs? How much is a jug of milk?

Question

Having a little trouble figuring this out! Hope someone out there can help me! Thank you in advance!

Answer 1

Let E = cost of box of eggs and M = cost of jug of milk

E + M = 5 

2E + 3M = 13

 

Multiply the first equation by 2 and subtract it from the 2nd equation to get M = 3

 

You finish it!
