Answer:

8. $35.10

9. $59.63

10. $13.43

11. $70

12. Take the percent you pay (100-the discount) as a decimal and multiply it by the regular price.

Step-by-step explanation:

For finding the price we pay during a sale, we focus on the percent we pay. If 22% off is the sale, then we spend 78% or 100-22-78. We use this percent byb  multiplying the price with a decimal. We convert percents into decimals by dividing the percent number by 100. For example, 78% divided by 100 becomes 0.78.

8. Percent off is 22%. We pay 78%=0.78.

45(0.78)=$35.10

9. Percent off is 33%. We pay 67%=0.67.

89(0.67)=$59.63

10. Percent off is 44%. We pay 56%=0.56.

23.99(0.56)=$13.43

11. Percent off is 75%. We pay 25%=0.25.

279.99(0.25)=$70

12. See explanation above.

3. The cost of the city permits needed to build this building is 150,000 no matter how many floors with
natima [27]

Answer:

P(x) = 150000

Slope = 0

Step-by-step explanation:

Given

Cost = 150000

Solving (a): The cost function:

From the given parameter, it shows that the number of floor has no effect on the floors.

So, represent the floors with x.

The cost function is:

P(x) = 150000

Solving (b): The slope and its interpretation

A function is represented as:

f(x) = b + mx

Where:

m=slope

By comparing: f(x) = b + mx to P(x) = 150000

m = 0

So:

Slope = 0

<em>What it means is that, no matter the number of floors, the cost remains unchanged.</em>
