Decide if the following change is an increase or decrease. then determine the percent of change. senior citizen receive a 10% discount off the price of a regular dinner special at the dinner bell restaurant. if the cost for a senior citizen to purchase a featured dinner special is $12.60, find the original price of a regular dinner special.

The oldster got a discount, so the original price is higher; let's call it x;

$14.00

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.
