Brian is a junior and is paid $18.42 per hour. Calculate
his weekly wage if he works 38 hours at the normal
rate and 6 hours overtime at time-and-a-half.

$865.74

Step-by-step explanation:

Time-and-a-half wage means you multiply the regular hourly rate by 1.5.

Regular wage: 38 hours at $18.42/hour

Time-and-a-half: 6 hours at 1.5 * $18.42/hour

Total weekly wage:

38 hours at $18.42/hour + 6 hours at 1.5 * $18.42/hour =

= 38 * $18.42 + 6 * 1.5 * $18.42

= $699.96 + $345.78

= $865.74

His weekly wage is $865.74

The mortality rate due to the roller skating is 10%

Step-by-step explanation:

Given:

Population of the city = 100,000

Number of skaters in Funville during any given month = 12,000

Roller-skating accidents in Funville = 600

Total number of residents injured from roller-skating = 1,800

number of deaths from roller-skating = 90

Total number of deaths from all causes = 900

Now,

The cause-specific mortality rate (from roller skating) in Funville

=

=

= 10%

Hence,

The mortality rate due to the roller skating is 10%
