A certain motorcycle manufacturer has been building motorcycles for 98 years. Over that period, production has increased steadil
Reika [66]

Answer: The fraction would be 0.53.

Step-by-step explanation:

Since we have given that

r(t)=A.(1.05)^t

where, A is the constant initial production rate

t is the time.

For 98 years, the production rate in motorcycles per year would be

r(98)=A.(1.05)^{98}\\\\r(98)=A.119.27

For 13 years, the production rate in motorcycles per year would be

r(98-13)=r(85)=A.(1.05)^{85}\\\\r(85)=A.63.25

So, the fraction of their total production was built during the last 13 years would be

\dfrac{r(85)}{r(98)}=\dfrac{63.25}{119.27}=0.53

Hence, the fraction would be 0.53.

Paul Smith pays $50.00 a month for group health insurance. There is a $300 deductible. His medical bills for the last year were
sergiy2304 [10]

Answer:

$1,360

Step-by-step explanation:

Take the monthly payment of $50 and multiply it by 12 because there is 12 months in a year which is $600. Next subtract $2,600 by your deduction of $300 which is $2,300. Then multiply by 20% because the insurance pays 80% leaving you with 20%, you get $460. Add $460 and $300 because those are the amounts you paid and you get $760. Now add the $600 to the $760 because of the monthly payment. The total comes out to $1,360.
