25) Jean is making a dry rub based on a recipe his friend from the United States sent to him, but he needs to convert ounces to grams to understand the recipe. If the rub requires 4 ounces of cayenne for every 7 ounces of paprika and there is 91 total ounces of paprika in the rub, how many total grams of cayenne and paprika are required?

(1 ounce=28.3 grams)

1. 5,148 grams
2. 4,926 grams
3. 4,522 grams
4. 4,047 grams

⁴/₇=^x/₉₁
CROSS-MULTIPLY 7x=364
D7 x=52

⁴/₇=⁵²/₉₁
These two fractions are equivalent to one another, so we know 52 equals x. 
Since we're looking for the total grams of both ingredients, it's necessary to add 52 and 91, then multiply the product times 28.3 grams. This gets you to Answer 4 as the correct response.
