Try to use y=Mx+b and if that doesn’t help just say so and I will help even more
Answer: 24 miles.
Step-by-step explanation:
1. You must keep on mind that, according the scale on the map, 1.5 inches represents 4 miles. Then, you can set up the following ratio:

Where x is the number of actual miles asked
2. You must solve for x, as following:

3. Therefore, 6 inches on the map represents 24 miles.
Part A:
Given that Rachel is planning a wedding for 100 to 250 people, the <span>inequality in terms of p people that describes how many people Rachel plans to invite is given by:
100 ≤ p ≤ 250
Part B:
Given that the </span>caterer charges $20 per person, plus a flat fee of $200,<span> the </span><span>inequality that shows how much the caterer will charge in terms of p is given by:
20(100) + 200 ≤ 20p + 200 ≤ 20(250) + 200
</span>
Part C:
<span>The range of catering fees (C) that Rachel is considering is given by:
</span><span>20(100) + 200 ≤ 20p + 200 ≤ 20(250) + 200
2000 + 200 ≤ C ≤ 5000 + 200
2200 ≤ C ≤ 5200
Therefore, the range of catering fees Racheal is considering is from $2,200 to $5,200

Find the discount price and subtract from the total to find the sale price.
To find the discount price, multiply 90 b 40% (convert 40% into decimal)
90 x 0.4 = 36
Next, subtract the discount from the total to find the sale price.
90 - 36 = 54
So, the sale price is <u>$54</u>.
