Answer:
The inequality to describe the problem is 15 +c >25.
We must sell more than 5 cones to make a profit
Step-by-step explanation:
From this problem, we can see that we need to sell a number of cones (c), that when added to the 15 cones that we have already sold, the result will be greater than 25.
To set up the inequality sign, we need to, first of all, know the inequality sign that we will be using. From the preceding statement, we can see that we need to sell greater than a certain number of cones.
This should tell us that we will be needing the greater-than sign (>).
The next step is to know the format the equation should take:
We have sold 15 cones; We need to sell c more to make it greater than 25.
This will be 15 +c >25.
The inequality to describe the problem is 15 +c >25.
from this, we can see that c > 5 cones.
We must sell more than 5 cones to make a profit
