Final answer:
To find the percent of savings on the beverage, subtract the final cost from the original cost and divide that amount by the original cost. Then, multiply the result by 100%. Rounding to the nearest whole percent, Mr. Ingram's savings are 18%.
Step-by-step explanation:
The question involves calculating the percent of savings Mr. Ingram had on the cost of a beverage. To find the savings percentage, we first determine the amount saved by subtracting the final cost from the original cost. The original cost was $44.19, and Mr. Ingram paid $36.18, so the saving is:
\[Savings = Original\;Cost - Final\;Cost\]
\[Savings = $44.19 - $36.18 = $8.01\]
Next, we calculate the savings percent by dividing the savings by the original price and then multiplying by 100:
\[Percent\;of\;Savings = \left(\frac{Savings}{Original\;Cost}\right) \times 100\%\]
\[Percent\;of\;Savings = \left(\frac{$8.01}{$44.19}\right) \times 100\% \approx 18.12\%\]
When rounded to the nearest whole number, Mr. Ingram's percent of savings is 18%, which corresponds to option C.
