Write an equation to represent Catherine's profit (p) from selling cupcakes for one month Catherine sells cupcakes, c, for 1.50
Archy [21]

Answer:

\text{p}=\$1.20\text{c}-\$20

Step-by-step explanation:

GIVEN: Catherine sells cupcakes c for \$1.50 each, The ingredients for each cupcake cost her \$0.30, and the sum of all her other expenses is \$20/\text{month}.

TO FIND: Equation to represent Catherine's profit from selling cupcakes.

SOLUTION:

Cost of ingredients for each cupcake  =\$0.30

sum of all other expenses  =\$20/\text{month}

Selling price of each cupcake =\$1.50

Total cupcakes sold =\text{c}

Now,

As we know that \text{Net profit}=\text{Selling price}-\text{Cost price}-\text{Other expense}

putting values,

                      \text{p}=\$1.50\text{c}-\$0.30\text{c}-\$20

                      \text{p}=\$1.20\text{c}-\$20

Hence the equation  to represent Catherine's profit (p) from selling cupcakes for one month Catherine sells is \text{p}=\$1.20\text{c}-\$20

On a piece of paper , graph f(x)=2^x then determine which answer choice matches the graph you drew.
amid [387]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

f(x)=2^x

This is a exponential function of the form

y=a(b^x)

where

a is the initial value or the y-intercept

b is the base of the exponential function

If b>1 then is a exponential growth function

If b<1 then is a exponential decay function

In this problem

The y-intercept is equal to

For x=0

f(x)=2^0=1

The y-intercept is the point (0,1)

so

a=1

b=2

The value of b is greater than 1

so

Is a growth function

To plot the graph create a table with different values of x and y

For x=-1

f(x)=2^-1=0.5

point (-1,0.5)

For x=1

f(x)=2^1=2

point (1,2)

For x=2

f(x)=2^2=4

point (2,4)

For x=3

f(x)=2^3=8

point (3,8)

For x=4

f(x)=2^4=16

point (4,16)

Plot the y-intercept and the other points and connect them to graph the exponential function

Note that as x increases the value of y increases (exponential growth function)

kvv77 [185]
Step by step explanation

Cost of one hotdog =140/56=2.5

To find the number of hot dogs =total cost so the cost of one hotdog is =175/2.5=70

So the numbers of hot dogs he had to sell more of =70-56=14
