Hint:
(2x+50) + 3x + 90 = 180
Solve for x first.
Then plug x into 2x + 50 and 3x.
Whichever gives you the smaller number is the answer.
The last option. would be correct
Answer:
This is a curve linear would show the turning points clearly.
With bar graph we can also show changes but not turnng points a sthe description shows.
Step-by-step explanation:
In the context of curve fitting, a linear curve is a curve that has a linear dependence on the curve parameters. Examples of linear curves are: lines, polynomials, so where they increase the points can also show a line of fit where least amounts would stand out below the line of fit.

Hope you can learn this, you should of just multipled 200 by .30 and then divided that by 20!
