It would be $40.50 because the pens are 27 pounds and the first 20 office supplies are $12, the next 30 are $10, and the remaining 37 would be $18.50
Subtract 14x from both sides. Then divide both sides by 19

The equation is now in slope intercept form y = mx+b
m = -14/19 is the slope
b = 20/19 is the y intercept
Yes! B is the correct answer
The answer is the given expression is 5 times as large as (1742-918)
