Answer:
x < 3
Step-by-step explanation:
Apply distributive property on the left of the inequality to get rid of the parenthesis:
8+4x > 5x+5
subtract 4x from both sides to group all terms with x on the right:
8 > 5x-4x+5
8 > x +5
Now subtract 5 from both sides to collect all numerical terms on the left:
8 - 5 > x
3 > x
Therefore the solution to the inequality are of those real numbers strictly smaller than 3.
The inequality can be written as x < 3 or also as we had it initially: 3 > x
Notice that the opening of the angle symbol is always facing the number 3 , meaning that 3 is the larger of the two numerical objects that are compared.
Based on the given situation above and given that the Cost is C and x is for the credit hours taken, and that per hour is $160 with an additional $50 to it, the equation would be like this: C(x) = 160x + 50. So the correct answer would be option C.
