Answer:
the definition of a market in determining the price elasticity of demand
Explanation:
In economics, the price elasticity of demand is the measure used to determine the responsiveness and the elasticity of a quantity demanded for a good or a service to increase in the price when nothing but only the price of the product changes. It is the measure to show the demand of a product in relation to the price change of the product.
In the context, Juan Carlos is is filling up a survey regarding the demand or purchasing of toothpaste when the price of the toothpaste changes. Thus this is important to study the price elasticity of demand of a product in the market economy.

Answer:
Keir will have the most money to spend on a new boat at the end of the five years; $1,440
Explanation:
Three friends decide that they each want to be able to buy a new boat in five years. Vanore puts $1,000 in a savings account with a simple interest rate of 4.5%. Keir invests $1,200 in a standard savers account with a simple interest rate of 4%. Omar invests $950 in a junior achievers account with a 6% annual compound interest rate. Who will have the most money to spend on a new boat at the end of the five years?
Vanore puts $1,000 in a savings account with a simple interest rate of 4.5%.
Vanore:
I = p * r * t
= 1000 * 0.045 * 5
= $225
I = $225
After 5 years, Vanore will have $1000 + $225
= $1225
Keir invests $1,200 in a standard savers account with a simple interest rate of 4%
Keir:
I = p * r * t
= 1200 * 0.04 * 5
= 240
I = $240
After 5 years, Keir will have $1200 + $240
= $1,440
Omar invests $950 in a junior achievers account with a 6% annual compound interest rate.
Omar:
A = P (1 + r)^t
= 950(1 +0.06)^5
= 950(1.06)^5
= 950(1.3382)
= 1271.1
A = $1,271.1
After 5 years, Omar will have $1,271.1
Keir will have the most money to spend on a new boat at the end of the five years; $1,440
