Question 890501

A person wants to purchase two types of items, 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.
<pre>
Let items A and B, be x, and y, respectively
Then we get: {{{x + y >= 10}}} ------- (i)
Also, 10x + 30y = 200_____10(x + 3y) = 10(20)___x + 3y = 20 ----- (ii)
Graph inequality and equation and shade the necessary sections.

If you need a complete and detailed solution, let me know!!
