Answer:

Least xpensive = 19.95

Most xpensive = 39.95

Mean = (39.95 + 19.95)/2 = 29.95

Amount spent for half people = 5 × 29.95

Amount spent for half people = 149.75

Lower limit for amount of da other half = 19.95 × 5 = 99.75

Upper limit for amount of da other half = 39.95 × 5 = 199.75

Mean = (99.75 + 199.75)/2 = 149.75

Total amount spent (Mean) = 149.75 + 149.75 = 299.5

Best estimate is B) 310 becuz it is closest to 295.5

Answer:

310

Step-by-step explanation:

least money 19.95

Most money = 39.95

Mean = (least+most)/2 = 29.95

money for half people = 5 × (mean) 29.95

Amount of money for half people = 149.75

Lower limit for amount of the other half = 19.95 × 5 = 99.75

The Upper limit for the amount of the other half = 39.95 × 5 = 199.75

Mean = (99.75 + 199.75)/2 = 149.75

Total money spent (Mean) = 149.75 + 149.75 = 299.5

The Best estimate is B) 310 because it is closest to 295.5
