To create algebraic expressions that represent quantities, translate the verbal description into mathematical terms following the sentence’s structure. For example, “one minus a number equals zero” becomes
1. 1 – n = 0.
Another example: John bought 25 apples and Julia bought 15. If Niccole bought twice as many as Julia, how many apples did Niccole buy?<span><span>
Steps:</span>First, restate the situation clearly so you can identify the relationship and how to form the expression.</span>
<span><span>
Solution:</span>Julia = 15 apples
Niccole = 2Julia
</span>Thus, 2Julia = 2(15) = 30 apples.
Answer:
- The profit can be expressed as 70x + 50
- If 240 phones are sold, the profit amounts to $16,850
Detailed explanation:
The revenue function R(x) is provided as 
The cost function C(x) is given as 
Profit is calculated by subtracting cost from revenue, expressed as Profit = Revenue − Cost
We substitute the given revenue and cost functions into this formula.
Denote the profit function as P(x).
Therefore, the profit function formula simplifies to 70x + 50
Since x denotes the quantity of phones sold, to find the profit when 240 phones are sold, we substitute x = 240 into the profit expression above.
Hence, selling 240 phones yields a profit of $16,850
The range consists of negative values. The interval for the range is. It may be beneficial to review your functions as there seems to be no available choice that aligns with this outcome. Step-by-step explanation: Given functions, we need to determine the range of. As I evaluate the domain as well to see if it alters the range. For the function, we need to avoid division by zero, meaning that the domain excludes zero. Consequently, the domain encompasses all real numbers except zero. Overall, the final conclusion remains that the range is solely negative numbers.
I think the rule to follow is to multiply the first number by the second and then add the first number. For example:
in the case of the first one, 1 x 4 = 4, then 4 + 1 = 5
for the second one, 2 x 5 = 10, and then 10 + 2 = 12...
So for 8+11:
simply multiply 8 x 11 = 88, and then add 88 + 8 = 96
I trust this will assist you.
