Answer
Find out the price of the shoes last week .
To prove
As given
The price of a pair of shoes is $52.
The price is 15% lower than last week.
15 % is written in the decimal form
= 0.15
15 % of the price of shoes = 0.15 × 52
= 7.8
The price of the shoes last week = price of a pair of shoes this week + 15 % of the price of shoes
= 52 + 7.8
= $ 59.8
As
1 dollar = 100 cent
59.8 dollar = 59.8 × 100
= 5980 cent .
Therefore the price of the shoes last week is 5980 cent .

Answer:
(a) As time increases, the amount of water in the pool increases.
11 gallons per minute
(b) 65 gallons
Step-by-step explanation:
From inspection of the table, we can see that <u>as time increases, the amount of water in the pool increases</u>.
We are told that Ann adds water at a constant rate. Therefore, this can be modeled as a linear function.
The rate at which the water is increasing is the <em>rate of change</em> (which is also the <em>slope </em>of a linear function).
Choose 2 ordered pairs from the table:
Input these into the slope formula:
Therefore, the rate at which the water in the pool is increasing is:
<u>11 gallons per minute</u>
To find the amount of water that was already in the pool when Ann started adding water, we need to create a linear equation using the found slope and one of the ordered pairs with the point-slope formula:
When Ann had added no water, x = 0. Therefore,
So there was <u>65 gallons</u> of water in the pool before Ann starting adding water.
