Question 4 (Fill-In-The-Blank Worth 2 points)

Maya and Sally were the two finalists in a singing competition. The person with the most votes from the audience was chosen as the winner. Sally received 25% of the total votes and lost by 62,500 votes. No person in the audience was allowed to vote more than once. The equation below represents this situation, where y is the total number of votes cast and x is the number of votes Maya received.

x - 62,500 = 0.25y

If a total of 125,000 people voted, how many votes did Maya receive?

Question 5 (Fill-In-The-Blank Worth 2 points)

The table below shows the fees to check bags on a certain airline.



If x represents the total number of bags a person checks and each person checks more than two bags, the equation below can be used to determine C, the total fee for all the bags.

20 + 25 + 50(x - 2) = C

Arianna paid a total of $145 to check all her bags on a flight. How many bags did she check in all?

yeah

Answer 6

Okay

Answer 7

@zordoloom yo can you help me also with these equations, and @Miyuru thank you for helping me too ,

Answer 8

@mayankdevnani help me too, need to get these done

Answer 9

Anyone gonna help me??

Answer 10

Man, you really seem to need way too much help.

For Question 1,

Equation: C = 0.765x + 0.06(0.765x)

Plug 100 where there is x, and solve. I'll guide you.

I wanna see you solve at least a few of these.

Answer 11

Let me know what you get.

Answer 12

U are welcome @jlongSwag27

Answer 13

Question 4

A store offers a 15% discount on all items in the store during a sale. All store employees get an additional 10% employee discount. In the equation below, C represents the cost of an item for an employee including tax, and x represents the original price of the item.

C = 0.765x + 0.06(0.765x)

Chris is an employee at the store. He plans to buy a coat during the sale. The price of the coat before the discount is $100. How much will Chris pay for the coat during the sale?

Answer for Blank 1:

ANSWERS: 1) C = coach; T = Tim
C = T + 10;
C-3 = 2(T-3), so C = 2T - 6 + 3 = 2t - 3
2t - 3 = t + 10
t = 13, Tim's age now, so coach is 23; three years ago they were 10 & 20

2) x - 62,500 = 0.25y; If a total of 125,000 people voted, how many votes did Maya receive?

x = Maya, y = total, = 125,000
x - 62500 = 0.25(125,000) = 31,250
x - 62500 = 31,250
x = 62500 + 31250 = 93,750 votes for Maya

3) sum of three consecutive integers is 267. What is the largest integer?

a + b + c = 267 Since they are consecutive, b = a + 1, c = a + 2. Substitute
a + a+1 + a+2 = 267
3a + 3 = 267
3a = 264
a = 88, b = 89, c = 90

4) C = 0.765x + 0.06(0.765x) Substitute 100 for x
C = 0.765(100) + 0.06(0.765)100 = 76.5 + (.06)76.5 = 1.06(76.5) = 81.09
He pays $76.50 for the coat, the 6% tax of $4.59

Answer 42

This post is getting way too long. With too much extra posts. It might be wise to repost this question. Good luck.
