Question

practice 1 on saturday and sunday, jarrod went running and burned a total of 647.5 calories. he burned 320 of those calories on saturday. write an addition equation that could be used to find the number of calories jarrod burned on sunday. (example 1)

Explanation:

Step1: Define variable for Sunday calories

Let $x$ = calories burned Sunday.

Step2: Set up total calories equation

Total = Saturday + Sunday:
$$320 + x = 647.5$$

Step3: Solve for $x$

Subtract 320 from both sides:
$$x = 647.5 - 320$$
$$x = 327.5$$

Answer:

Addition equation: $320 + x = 647.5$
Calories burned Sunday: $327.5$
