123 + x = 180
-123. -123
x = 57
the answer is C.
C=1.67n
It's kind of like y=mx+b. C stands for the overall price. And n stands for the amount of pounds. For example if someone bought 6 pounds apples at the farm it would be
c=1.67(6)
c= $10.02
What are you trying to solve dear
A
2 x 8+16 = 32 16 x 4 = 64
B
2 x 4 +8 = 16 8 x 8 = 64
C
4 x 8 + 32 = 64 2 x 32 = 64

The teacher has 64 or more pencils to give out.
