Question 5

5.

You want to buy some specialty cooking ingredients online, but the specific brand of mouth-numbing Szechuan peppercorns you're looking for is not available from Congo, your favorite rainforest-themed online shopping site. So you won't get free shipping 😥 . Instead, you narrow it down to two specialty foods websites.

SpiceWorld offers the spice for $2.25 per ounce, with a $5.99 shipping fee.
ChinaFlavor offers the spice for $3.25 per ounce, but with only a $1.99 shipping fee.

Let x be the number of ounces of Szechuan peppercorns you will buy. Write an inequality that will help determine for what size orders it is cheaper to buy from ChinaFlavor than from SpiceWorld

Which online vendor is the best choice for Terrance? Why? (For partial credit, make sure to explain how much spice Terrance needs and when it's cheaper to buy from which vendor.)
