A spice store charges $2.75 for 25 grams of paprika. It also charges 5% of the purchase price for shipping any order

zlopas [31]

Answer:

Part a) The expression is $3.2445x$

Part b) Customer cannot buy 2.5 ounces of paprika and have it shipped for less than $8.00

Step-by-step explanation:

<u><em>The complete question is</em></u>

A spice store charged 2.75 for 25 grams of paprika. It also charges 5% of the purchase price for shipping any order.

Part a) Write and simplify an expression to determine the cost of buying and shipping x ounces of paprika. Use 1 ounce = 28 grams

Part b) Can a customer buy 2.5 ounces of paprika and have it shipped for less than 8.00? Explain

step 1

Convert grams to ounces

Remember that

$1\ oz=28\ g$

To convert grams to ounces divide by 28

$25\ g=25/28= 0.89\ oz$

The unit price is

$2.75/0.89=3.09\frac{\$}{oz}$

Let

x ----> the number of ounces of paprika

y ----> the cost of buying and shipping x ounces of paprika

5%=5/100=0.05

$y=3.09x+(3.09x)0.05\\y=3.09x[1+0.05]\\y=3.2445x$

Part b) For x=2.5 oz

substitute in the equation

$y=3.2445(2.5)=\$8.11$

$\$8.11 > \$8.00$

therefore

Customer cannot buy 2.5 ounces of paprika and have it shipped for less than $8.00

Which of the following functions is quadratic?

madam [21]

Answer:

f(x)=3(x-4)(x+3)

Step-by-step explanation:

Quadratic function follows the f(x) = ax^2 +bx+c pattern

f(x)=3(x-4)(x+3) after multiplying out is equal to

f(x)=(3x-12)(x+3) = (3x^2+9x-12x-36) = (3x^2-3x-36)

f(x) = (3x^2-3x-36)

where

a = 3

b = -3

c = -36

Write ln 2x + 2x ln x -ln 3y as a single logarithm.

andreev551 [17]

Answer: option c.

Step-by-step explanation:

To solve this problem you must keep on mind the properties of logarithms:

$ln(b)-ln(a)=ln(\frac{b}{a})\\\\ln(b)+ln(a)=ln(ba)\\\\a*ln(b)=ln(b)^a$

Therefore, knowing the properties, you can write the expression gven in the problem as shown below:

$ln2x+2lnx-ln3y=ln2x+lnx^2-ln3y\\\\=ln(2x)(x^2)-ln3y\\\\=ln(\frac{2x^3}{3y})$

Therefore, the answer is the option c.
