Question

I need help figuring out how to get a certain number of packets that equal a specific price please help!

Vanilla wafers are $4 and Chocolate is $1. If I spent $45 on 27 packets of wafers how many of both would I have of each?

Answer 1

if you mean vanilla wafers and chocolate wafers....
v + c = 27
4v + 1c = 45

now you can solve by substitution

Answer 2

I have tried that and I keep messing up and I just cant figure it out.

Answer 3

How have you tried that?

Answer 4

v + c = 27
v = 27 - c

4v + 1c = 45
4(27 - c) + 1c = 45
108 - 4c + 1c = 45
-4c + 1c = 45 - 108
- 3c = - 63
c = 21

v + c = 27
v + 21 = 27
v = 27 - 21
v = 6

Answer 5

because I have used that already
