The inequality for this problem would be 10.99c + 8.89b ≤ 25.
To find this, we need to know that for every pound of cashews (c) we have to pay 10.99. That's how we find the first term. Similar for the second in which we charge 8.89 for blueberries (b).
Then when we add these together, we know that they must not be greater than 25. So we can express it with a ≤.
A negative sign under a square root means that the root is a not a real number.
A negative sign outside a square root means we can "cover it" and evaluate the square root.
When the sign is outside, you can do the root first, then apply the sign. Not so if the sign is inside.
Thus, √-49 is not real and -√64 = -8.
Step-by-step explanation:
28.4 g there are 110 calories
1 g there are 110/28.4 = 3.87 calories
39.76 g there are 3.87 × 39.76 = 153.87
