Parent volunteers at Wildgrove High School are processing yearbook order forms. Students have an option to get the basic yearbook or a deluxe option, which includes engraving and a protective cover. In Mrs. Whitehead's class, 23 basic yearbooks and 30 deluxe yearbooks were ordered, for a total of $4,091. The students in Mr. Copeland's class ordered 19 basic yearbooks and 21 deluxe yearbooks, for a total of $3,058. How much does each option cost?

Step-by-step explanation:

ggg

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
