Question

James buys 3 ingredients for his dish for a total cost of $\$$69.38. The cost of each ingredient is as shown:


The cost of Ingredient 3 is .

• A. $\$$29.65
• B. $\$$29.55
• C. $\$$39.55
• D. $\$$39.65

Answer 1

The correct option is B $\$$29.55

Cost of Ingredient 1 = $\$$12.27

Cost of Ingredient 2 = $\$$27.56

Total cost of all 3 ingredients is
$\$$69.38.

Hence, the cost of Ingredient 3 can be calculated as:


Calculating 12.27 + 27.56 using the standard method, we get:


Hence, the combined cost of Ingredients 1 and 2 is $\$$39.83.

Now, to find the cost of Ingredient 3, we calculate the value of
$\$$69.38 - $\$$39.83

Calculating 69.38 - 39.83 using the standard method, we get:


∴ The cost of Ingredient 3 is $\$$29.55.
