Question

If 3 candy bars have 783 calories and 3 bars contain 792 calories, what is the caloric content of each candy bar? a) 260 calories per bar b) 263 calories per bar c) 261 calories per bar d) 264 calories per bar

Answer 1

261 calories or 264 calories. Either it's c) or d).

Step-by-step explanation:

3 candy bars = 783 calories

3 candy bars = 792 calories

3 candy bars x Unknown calories = 783 calories x 3 candy bars

3 candy bars x Unknown calories = 792 calories x 3 candy bars

Unknown calories = (783 calories)/(1 bar) = 261 calories per bar

Unknown calories = (792 calories)/(1 bar) = 264 calories per bar
