A.$2,100.00
B.$2,300.00
C.$2,500.00---
D.$3,000.00
==================================
C = m N + b
1600 = m(650) + b
900 = m (300) + b
----------------------------subtract
700 = 350 m
m = 2
900 = 600 + b
b = 300
so
cost = 2 (number) + 300
for 1000
cost = 2300, so disagree with you
12/3 is not 13
11. is A
