Im the same person from my other questions!
Two stores sell the same computer for the same original price. Store A advertises that the computer is on sale for 25% off the original price. Store B advertises that it is reducing the computer’s price by $180. When Brittany compares the sale prices of the computer in both stores, she concludes that the sale prices are equal.
0.25p = p – 180
0.75p = p + 180
0.25(p – 180) = p
0.75p = p − 180 **
Nathan and Steven stacked boxes on a shelf. Nathan lifted 13 boxes and Steven lifted 15 boxes. The boxes that Nathan lifted each weighed 12 lb more than the boxes Steven lifted.
13(s +12)**
s + 12
15(s + 12)
12(s + 13)
.75 p = p - 180 yes
I do not know what the second question is.
For the second one: Which expression represents the total number of pounds Nathan lifted?
let s represent the weight of boxes Steven lifted.
13(s+12)
To compare the sale prices of the computer in both stores, we can use the given information and equations to solve for the original price of the computer (p).
From the given information, we know that Store A advertises a 25% discount, which means the sale price is 75% of the original price. Store B advertises a reduction of $180 from the original price.
The first equation 0.25p = p - 180 represents Store A's sale price (25% discount on the original price).
Simplifying the equation, we have:
0.25p = p - 180
0.25p - p = -180
-0.75p = -180
p = -180 / -0.75
p = 240
The original price of the computer is $240.
Now, let's compare the sale prices in both stores:
For Store A, the sale price is 25% off the original price, which is equal to:
0.25 * 240 = $60 off the original price.
For Store B, the reduction is $180 from the original price.
Since Brittany concludes that the sale prices in both stores are equal, we can set up the equation:
Sale price at Store A = Sale price at Store B
(Original price - Discount at Store A) = (Original price - Reduction at Store B)
Substituting the values we found:
(240 - 60) = (240 - 180)
Simplifying the equation:
180 = 60
But this is not a true statement. We made an error in one of the equations or calculations. Please double-check the provided equations and information for accuracy.
Moving on to the second question:
Nathan and Steven stacked boxes on a shelf. Nathan lifted 13 boxes, and Steven lifted 15 boxes. It is mentioned that the boxes Nathan lifted each weighed 12 lb more than the boxes Steven lifted.
To represent this, we can use the equation:
Weight of boxes Nathan lifted (13 boxes) = Weight of boxes Steven lifted (15 boxes) + 12 lbs
Let's assign a variable to represent the weight of the boxes Steven lifted. Let s be the weight of each box Steven lifted in pounds.
The equation can be written as:
13(s + 12) = 15s
Expanding the equation:
13s + 156 = 15s
To solve for s, we can subtract 13s from both sides:
156 = 2s
Dividing both sides by 2:
s = 78
The weight of each box Steven lifted is 78 lbs.
Therefore, the weight of each box Nathan lifted would be:
s + 12 = 78 + 12 = 90 lbs
To summarize:
- The weight of each box Steven lifted is 78 lbs.
- The weight of each box Nathan lifted is 90 lbs (which is 12 lbs more than what Steven lifted).
