Use a ratio box to solve this problem. The price of one model of car increased 10 percent in one year. If the price this year is $17,600, what was the price last year

x2 + 2x -8<0

Step-by-step explanation:

Now we have the inequality; x2 + 2x -8<0. We have to solve it accordingly;

x^2 +4x-2x-8<0

x(x+4) -2(x+4) <0

(x+4) (x-2) <0

Hence the solution is (-4,2).

What we have now obtained is the same as the region required for the inequality hence this must be the correct option that we need to find in this question.
