1) The inequality that represents the fact that you can’t exceed this spending limit is; 11x + 10 ≤ 150
2) The situation modeled by the inequality is Option C.
3) The inequality that represents the given situation is; 30 - 3c ≥ 14
We are told;
Cost of purchasing each toy = $11 per toy
Shipping fee = $10 for all
Selling price of each toy = $13 per toy
Maximum amount for cost price = $150
1) The inequality that represents the fact that you can't exceed the $150 maximum cost price is;
11x + 10 ≤ 150
Where x is maximum number of toys you can purchase.
2) The inequality given is; 12x < 11x + 10
From earlier, we saw that the right hand side is $11 per toy and $10 shipping fee for company A.
Now, left hand side shows only 12x which is company B charging $12 per toy.
Thus, the situation modeled by the inequality is option C.
3) Let the number of customers that purchased 3 toys be c.
Since you bought 30 toys and c customers bought 3 toys. Then, toys left is;
30 - 3c
Now,we want this to be at least 14 toys. Thus;
30 - 3c ≥ 14
