Answer:

B) 275n + 1000 = 2700

Step-by-step explanation:

n is just a placer holder for how many days the Carter family can vacate.

That being said, the question says that they will spend 275 per day, which is per n. You want to multiply 275 by n.

Then the question says it plans to spend $1000 on meals (that's a lot). Instead of substracting, you are going to add for this equation. You want the equation to match; you want both sides to equal 2700 so you can determine how many days you can spend there.

Pls help with my 10 gr math
Anna35 [415]

Lets review the options one by one:

X A.) The question says the y must be <u>less than</u> 100, not less than or equal to.

X B.) The y becomes 0, but 0 is neutral, not a positive number.

X C.) The height must be positive at all times, according to the range given.

√ D.) The given graph contains a max with a positive number under 100.

Therefore, the correct answer choice would be Option D (4).

<em>Hope this helps! :)</em>
