Answer:31
Step-by-step explanation:
You subtract 81 and 50
y = cost = $25
25 = 0.75 +10
subtract 10 from each side
15=0.75x
x = 15/0.75 = 20

Yes you are correct. You divide both sides by -6 to isolate x. Dividing both sides by a negative number will flip the inequality sign.
If you need to graph this, then you'll have a closed circle at -12 on the number line. Then you'll have shading to the left of this closed circle. The closed circle indicates "include this endpoint as part of the shaded solution set".
