Using simple mathematical operations, the missing values are as follows:
(B) Dijon Mustard: 18g
(C) Barbeque sauce: 70g
- Increased by 5 = 350g
- Increased by 20 = 1,400g
(D) Worcestershire sauce: 10.35g
- Increased by 5 = 51.75g
- Increased by 20 = 207g
(E) Kosher salt: 1.5g
- Increased by 5 = 7.5g
- Increased by 20 = 30g
(F) Ground black pepper: 2.3g
- Increased by 5 = 11.5g
- Increased by 20 = 46g
(G) Crushed red pepper: 1.15g
- Increased by 5 = 5.75g
- Increased by 20 = 23g
<h3>
What do we mean by mathematical operations?</h3>
- A mathematical "operation" is the process of calculating a value utilizing operands and a math operator.
- There are predefined rules associated with the math operator's symbol that must be applied to the supplied operands or numbers.
- The order of operations is a rule that outlines the proper steps to take when analyzing a mathematical equation.
- We can recall the PEMDAS steps in the following order: Parentheses, Exponents, Multiplication, Division (from Left to Right), Addition, and Subtraction (from left to right).
So, we can calculate missing values as follows:
(B) Dijon Mustard: 18g
- Increased by 20 = 18×20 = 360g
(C) Barbeque sauce: 70g
- Increased by 5 = 70×5 = 350g
- Increased by 20 = 70×20 = 1,400g
(D) Worcestershire sauce: 10.35g
- Increased by 5 = 10.35×5 = 51.75g
- Increased by 20 = 10.35×20 = 207g
(E) Kosher salt: 1.5g
- Increased by 5 = 1.5×5 = 7.5g
- Increased by 20 = 1.5×20 = 30g
(F) Ground black pepper: 2.3g
- Increased by 5 = 2.3×5 = 11.5g
- Increased by 20 = 2.3×20 = 46g
(G) Crushed red pepper: 1.15g
- Increased by 5 = 1.15×5 = 5.75g
- Increased by 20 = 1.15×20 = 23g
Therefore, using simple mathematical operations, the missing values are as follows:
(B) Dijon Mustard: 18g
(C) Barbeque sauce: 70g
- Increased by 5 = 350g
- Increased by 20 = 1,400g
(D) Worcestershire sauce: 10.35g
- Increased by 5 = 51.75g
- Increased by 20 = 207g
(E) Kosher salt: 1.5g
- Increased by 5 = 7.5g
- Increased by 20 = 30g
(F) Ground black pepper: 2.3g
- Increased by 5 = 11.5g
- Increased by 20 = 46g
(G) Crushed red pepper: 1.15g
- Increased by 5 = 5.75g
- Increased by 20 = 23g
