Answer 5

To calculate the tip, we multiply the cost of the dinner by the percentage of the tip, which in this case is 35%.

35% of $56.25 is 0.35 * $56.25 = $19.69.

Therefore, Rafeal should provide $19.69 as a tip.

Answer 6

To find the percent error, we need to compare Layla's prediction to the actual number of occupied seats.

The actual number of occupied seats is 81,500, while Layla predicted 79,000.

The equation for percent error is: (|predicted - actual| / actual) * 100

Using this equation, the calculation for percent error is: (|79,000 - 81,500| / 81,500) * 100 = (2,500 / 81,500) * 100 = 0.03067 * 100 = 3.07

Therefore, the percent error of Layla's prediction is approximately 3.07%.

Answer 7

To find the percent error, we need to compare Aatikah's predicted cost to the actual cost.

The predicted cost is $30.00, while the actual cost is $19.75.

The equation for percent error is: (|predicted - actual| / actual) * 100

Using this equation, the calculation for percent error is: (|30.00 - 19.75| / 19.75) * 100 = (10.25 / 19.75) * 100 ≈ 51.9

Therefore, the percent error in Aatikah's prediction is approximately 52%.

Answer 8

To find the percent error, we need to compare Julian and Brittany's predicted number of attendees to the actual number of attendees.

The predicted number of attendees is 275, while the actual number of attendees is 265.

The equation for percent error is: (|predicted - actual| / actual) * 100

Using this equation, the calculation for percent error is: (|275 - 265| / 265) * 100 = (10 / 265) * 100 = 0.03774 * 100 ≈ 3.77

Therefore, the percent error in Julian and Brittany's prediction is approximately 3.77%.
