Answer:

Explanation:

The percent of the decrease can be calculated as:

[tex]\text{ \% decrease = }\frac{\text{ Initial value - Final value}}{Initial\text{ value}}\times100[/tex]

So, replacing the initial value with 150 calories and the final value by 78 calories, we get:

[tex]\text{ \% decrease = }\frac{150-78}{150}\times100=48\text{ \%}[/tex]

Therefore, the percent of decrease is 48%
