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 televisions 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 televisions original price.

0.7p = (p - 250)

Step-by-step explanation:

Let the original price of the television is $p.

Store advertises that the television was on sale with 30% off the original price p.

So the price of television after 30% discount = p - 30% of the original price

= p -

= p - 0.30p

= 0.70p

Other store B reduced the price of television by $250

So the cost of television after discount = p - 250

When Allison compared the prices in both the stores, prices of the television were equal.

Equation that models the situation will be

0.70p = (p - 250)

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
