Question

Tom wants to make an omelet for breakfast. Usually, he makes omelets for his family of four and uses a recipe that calls for 10 eggs, 4.8 grams of butter, 3 tablespoons of pepper, and 1 teaspoon of salt. However, today Tom is only making an omelet for himself using $e$ eggs, $b$ grams of butter, $p$ tablespoons of pepper, and $s$ teaspoons of salt. What is $e+b+p+s$ expressed as a decimal? Assume all four family members eat the same sized omelettes.

Answer 1

Answer: 4,7

Explanation:

Eggs: 10/4: 2,5

grams of butter: 4.8/4: 1,2

tablespoons of pepper: 3/4: 0,75

teaspoon of salt: 1/4: 0,25

2,5 + 1,2 + 0,75 + 0,25= 4,7
