Question

Two stores sell the same television for the same original price. Store A advertises that the television is on sale for 30% off the original price. Store B advertises that it is reducing the television's price by $250. When Allison compares the sale prices of the television in both stores, she concludes that the sale prices are equal.

Which equation models this situation?

Let p represent the television's original price.

A.
0.3p = p - 250

B.
0.7p = p - 250

C.
0.3p = p + 250

D.
0.7(p - 250) = p

Answer 1

At 30% off, how much is the discount?
It is 30% of the original price.
The original price is p. What is 30% of p?

Answer 2

umm.... b?

Answer 3

Forget the answers for now.
How would you write in math 30% of p?

Answer 4

What is 30% as a decimal number?

Answer 5

.3

Answer 6

OHHH

Answer 7

ITS A

Answer 8

yes

Answer 9

zank you everyone

Answer 10

Great.
30% is 0.3
30% of p is 30% times p, so it is 0.3p

Answer 11

The discount is 0.3p
If the entire cost is p, and you take off 0.3p, you are left with 0.7p.
The price actually paid is 0.7p

Answer 12

We are told the discount is $250.
That means the actual price paid is p - 250

Answer 13

Now we equate these two things to get the correct equation:
0.7p = p - 250

Answer 14

The answer is B, not A.
