Assume that price is an integer variable whose value is the price (in US currency) in cents of an item. Assuming the item is pai
cestrela7 [59]

Answer:

Change = (Paid*100) - Price

Step-by-step explanation:

First of all we need to know the relation between 1 dollar and 1 cent in order to express everything in the units required in the question.

We know that 1 dollar = 100 cents, so the amount paid for the item with single dollars has to be multiplied by 100 to express its value in cents.

Paid_{cents}=Paid_{dollars}*100

Now that we have everything in cents, we can make the subtraction:

Change_{cents} = Paid_{cents} -Price_{cents}

Replacing the value in cents we get:

Change = (Paid*100) - Price

A political polling agency predicts candidate A will win an election with 63% of the votes. Their poll has a margin of error of
scoray [572]

Answer:

56% ≤ p ≤ 70%

Step-by-step explanation:

Given the following :

Predicted % of votes to win for candidate A= 63%

Margin of Error in prediction = ±7%

Which inequality represents the predicted possible percent of votes, x, for candidate A?

Let the interval = p

Hence,

|p - prediction| = margin of error

|p - 63%| = ±7%

Hence,

Upper boundary : p = +7% + 63% = 70%

Lower boundary : p = - 7% + 63% = 56%

Hence,

Lower boundary ≤ p ≤ upper boundary

56% ≤ p ≤ 70%
