Answer:
f = 
Step-by-step explanation:
1. 4(4f - 9) = -(2-f) distribute the negative
2. 4(4f - 9) = -2 + f Distribute the 4
3. 16f - 9 = -2 + f Subtract f on both sides
4. 15f - 9 = -2 Add 9 on both sides
5. 15f = 7 Divide both equations by 15
6.
f = 
Answer:
x = 8
Step-by-step explanation:
2x + 46 = 7x + 6
Add -2x and -6 on both sides.
46 - 6 = 7x - 2x
40 = 5x
Divide 5 into both sides.
40/5 = x
8 = x
Well 16 ounces equals a pound. So 16+16=32 ounces.
So 32 ounces times $0.30 equals 9.6.
So 2 lbs should cost $9.6.
