A bakery has the following pricing for large orders of cupcakes. The first 100 cupcakes of any order

Taya2010 [7]

A piecewise function is a function that behaves differently in different intervals of its domain.

The answers are:

a)

f(x) = x*$2.00 if 0 ≤ x ≤ 100

f(x) = x*$1.75 if 100 < x ≤ 250

f(x) = x*$1.25 if x > 250.

b) $306.25

The given information is:

The first 100 cupcakes cost $2.00 each.

If the order is between 100 and 250 cupcakes, the cost is $1.75 each.

If the order is more than 250 cupcakes, the cost is $1.25 each.

a) Now we want to write the piecewise function, this will be:

f(x) = x*$2.00 if 0 ≤ x ≤ 100

f(x) = x*$1.75 if 100 < x ≤ 250

f(x) = x*$1.25 if x > 250.

Above you can see the piecewise function, when you want to evaluate it, the first thing you need to do is to find at which interval the input belongs.

b) If you order 175 cupcakes you have x = 175.

This belongs to the second interval ( 100 < x ≤ 250) then we will use the second part of the function:

f(175) = 175*$1.75 = $306.25

There are four defenders on a soccer team. if this represents 20 percent of the players on the team, which equation can be used

Amiraneli [1.4K]

Given

There are four defenders on a soccer team

if this represents 20 percent of the players on the team

Find out the total number of players on the team.

To proof

As given in question

four defenders on a soccer team

this represents 20 percent of the players on the team

let the total number of players = x

First convert 20% in the decimal form

$\frac{20}{100} =0.20$

Than the equation becomes

0.20x =4

$x = \frac{4}{0.20}$

now solving the above equation

we get

x = 20

thus the total number of players on the team are 20.

Hence proved

Answer:

Monthly household expenditures on groceries

Step-by-step explanation:

The response variable is the one for which measurements are desired and that depends on other variables.

In this case, family size, household income, and household neighborhood are independent variables, while the response variable is the monthly household expenditures on groceries.
