Answer 2

I will be more than happy to give you a direct explanation.

First, you must use the information to create 2 equations
you solve those by any method of elimination in order to get the values needed.

I would suggest you choose some variables, I did A = carrots and R = crackers.

Can you write the 2 equations?

Answer 3

a + r = 6.03

Answer 4

cost was 6.03
so that should be
2.10a + 2.90r = 6.03

pounds are 2.3
so that should be
a + r = 2.3

Answer 5

it's c or d

Answer 6

by solving the equations we can get our answer.
a + r = 2.3
2.10a + 2.90r = 6.03

multiply first equation by -2.10 (each term)

now you can eliminate A and solve for R which tells you your pounds of crackers :)
