Answer:

Part a) The expression is [tex]3.2445x[/tex]

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

Step-by-step explanation:

The complete question is

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

[tex]1\ oz=28\ g[/tex]

To convert grams to ounces divide by 28

[tex]25\ g=25/28= 0.89\ oz[/tex]

The unit price is

[tex]2.75/0.89=3.09\frac{\$}{oz}[/tex]

Let

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

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

5%=5/100=0.05

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

Part b) For x=2.5 oz

substitute in the equation

[tex]y=3.2445(2.5)=\$8.11[/tex]

[tex]\$8.11 > \$8.00[/tex]

therefore

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