Answer: $103
Explanation:
Stores will markup an item to make a profit so this question is asking how much they will be selling the shoes to the customer.
To solve this problem we will start by multiplying the price the store payed for (55.25) by the percentage in decimal form (.87)
55.25•0.87=48.0675
We then add the markup to the price payed for the shoes.
55.25+48.0675=103.3175
When rounding to the nearest dollar we look at the digit in the tens place (3) and since 3 is < 5 we round the final price to $103
The constant of variation based on the information is one half.
<h3>How to illustrate the information?</h3>
From the information given, when x is 2, y is 1, when x is 4, y is 2, etc.
Therefore, the constant of variation will be:
= y/x
= 1/2 = 2/4
= 1/2 = 1/2
Therefore, the constant of variation based on the information is one half.
