This week, the art museum gave away 1,200 tickets to the greco exhibit, which was 150 percent as many tickets as it gave away last week. martin is trying to figure out how many tickets the museum gave away last week. his work is shown below.

Step 1  1200/ ?

Step-by-step explanation:

There is a mistake in the very first step

He is writing par over whole

100% is the original amount of tickets x

150% is the 1200 tickets

150       1200

 =  

100          ?

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
