Question

A jumbo-size 90-ounce drink at a certain gas station has 730 calories. How many calories are there in a 21-ounce drink?

A) 166.67 calories
B) 182.22 calories
C) 255 calories
D) 273.33 calories

Answer 1

To find the number of calories in a 21-ounce drink, set up a ratio between the sizes of the two drinks and the number of calories they contain. The jumbo-size drink is 90 ounces and has 730 calories, so the ratio is 90/730.

Step-by-step explanation:

To find the number of calories in a 21-ounce drink, you can use the concept of ratios. Let's set up a ratio between the sizes of the two drinks and the number of calories they contain. The jumbo-size drink is 90 ounces and has 730 calories, so the ratio is 90/730. We want to find the number of calories in a 21-ounce drink, so we can write the ratio as 21/x. Cross-multiplying, we get 90x = 730 * 21, and solving for x, we find x = (730 * 21) / 90. Evaluating this expression gives us x = 166.67 calories.
