The number of $5 notes is 10 and $50 notes is 6

Step-by-step explanation:

Let x be the number of $5 notes

and

y be the number of $50 notes

Then according to given statements

"The total number of notes used was 16."

x+y=16    Eqn 1

"A restaurant bill of $350 was paid using $5 notes and $50 notes."

5x+50y=350       Eqn 2

From\ Eqn\ 1\\x+y=16\\y=16-x\\Putting\ y=16-x\ in\ equation\ 2\\5x+50(16-x)=350\\5x+800-50x=350\\-45x+800=350\\Subtracting\ 800\ from\ both\ sides\\-45x+800-800=350-800\\-45x=-450\\Dividing\ both\ sides\ by\ -45\\\frac{-45x}{-45}=\frac{-450}{45}\\x=10

Putting x=10 in equation 1

10+y=16\\y=16-10\\y=6

So,

The number of $5 notes is 10 and $50 notes is 6

Barbara can pay either $80 per month or one lump sum of $800 per year for car insurance. How much does she save yearly if she ch
Schach [20]

Answer:

$160

Step-by-step explanation:

In the monthly payment option she would pay $80 per month, therefore in a year (12 months) she would pay:

$80*12 =  $960

We can see that this amount is greater than the $800 she would pay in the lump sum payment option.

The money she would save is:

$960 - $800 = $160

She would save<u> $160 yearly</u> with the lump sum payment option.

50 (x+ 10) = 240<br> Whats the value for x
Katen [24]

Answer:

-26/5 or -5.2

Step-by-step explanation:

First, you need to expand the parentheses:

50x+500=240

Now, subtract 500 from both sides:

50x=-260

Now, divide both sides by 50

x=-26/5=-5.2

Hope this helps!

Because bernard has some health issues, he must pay 15% more for life insurance. about how much more annually will a $115,000 10
Sergeu [11.5K]

The amount more annually a $115,000 10-year term insurance at age 35 cost Bernard than someone of the same age without health issues is $24.

<h3>What are insurance premiums?</h3>

The insurance premium is paid as a cost to cover a possible loss that is unseen.

The annual premium rate as a percentage of the value insured a person at age 35 has to pay is 0.14%.

From the given information, we have that the amount a 35-year-old without health issues will pay per $1,000 is $1.40

The amount to be paid for $115,000 is 115 × $1.4 = $161

The amount Bernard pays = 15% more

= 1.15 × $161

= $185.15

Therefore,

The amount more Bernard has to pay = $185.15 - $161

= $24.15 ≈ $24
