Ms. nichols bought enough sandwiches to feed 28 people. each sándwich serves 2 people. the cost of one sándwich is 4.99.how much did ms. nichols pay for the sándwiches?

$70 (or $69.86)

Step-by-step explanation:

We know that she got enough sandwiches for 28 people and we know that each sandwich serves 2 people. This means that we have to divide 28 by 2 (because that gives us the amount of sandwiches she bought). If each sandwich is $4.99 (or rounded to $5), then we can multiply 5 by 14. This gives us 70. So, she payed $70 for the sandwiches.

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.
