Your grandmother wants to spend at least $40 but no more than $60 on school clothes for you. t-shirts sell for $10 and pants sell for $20. how many t-shirts and pants could she buy?
write a system of two inequalities that describes the situation.
write two possible solutions to the problem.

she could buy 2 pants and 2 shirts because 2 pants =$40 and 2 shirts=$20 so 40 +20=60

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.
