Question 848226
A and B from a shop. she has 200 to spend, and she has to purchase at least 10 items.
 if the price of one unit of each A and B is $10 and $30 respectively represent this problem graphically
:
Write an equation for the no. of items and for the cost of the items
put the equations in the slope/intercept so you can graph
A + B = 10
A = (10-B); Red
and
10A + 30B = 200
simplify, divide by 10
A + 3B = 20
A = (20-3B); Green
Graph it, A is on y axis, B is on the X axis
{{{ graph( 300, 200, -6, 20, -10, 20, 10-x, 20-3x) }}}
The area of possible combinations of A and B, is at or below the graphs and above 0
