We want to find 150% of 3000. since 150% is greater than 100%, it is expected that 150% 0f 3000 will also be greater than 3000.

Therefore, 150% of 3000 is equal to 4500.
To find a linear question, we must have two points on the line and we must know the slope.
Let us choose two points at random:
(-6,12) and (-5,14)
Now let us find the slope of the linear line:

So the slope is 2.
Now let us set up the equation which now requires only one point and the slope
let us use the point (-6,12) and the slope of 2

So the linear line is y = 2x + 4.
Hope that helps!

13: multiply the amount by the tax rate (to make a percent a decimal move the decimal point 2 places to the left) and add the original amount and the taxed amount together. For 12 do above but then multiply the total by the tip rate and add together (basically the same as the tax again) :) I hope this helps
