Answer:
f(X) 70x49
Step-by-step explanation:
-2x = -60
Isolate x and simplify.
2x = 60
x = 30
Straight vertical line through x=30.
70
20x(1+150%)
28x(1+1.5)
28x2.5
Answer: $3,300
because each chair costs about $150, and 22 chairs were sold, then the problem is 150x22. And 150x22 is $3,300.
You have to divide to unit price, 169/13 is equal to 13!
