This isn't the same problem but it's an idea. of what you're doing.
If I can work 15 hours, I would make more money at the restaurant.
If I can work more hours, I would make more money at my dad's office.
The job I would choose is the job at my dad's office. This is because I would earn more money at this job.
<h3>Amount earned at the dad's office</h3>
The amount of money I would earn at my dad's office can be determined by multiplying the pay per hour by the total number of hours I work.
Amount that would be earned at my dad's office = fixed earnings + variable earnings
$10 + ( $8 x 15) = $130.
<h3 /><h3>Amount earned at the restaurant</h3>
The amount of money I would earn at the restaurant, can be represented with this equation: ($5.50 x 15) + [0.6 x ($5.50 x 15)]
$82.50 + $49.50 = $132
<h3>Amount earned if I work extra hours</h3>
Amount I would earn at my dad's office if I work for 20 hours = (20 x $8) + $10 = $170
The amount of money I would earn at the restaurant if I work for 18 hours = ($5.50 x 18) + [0.6 x ($5.50 x 18)]
= $99 + $59.40 = $158.40

3 digits, there are 10 digits: 0, 1, ..., 9. Order matters 123 is a different code than 321, then
Possible codes: 10 * 9 * 8 = 720, since it can not be repeated.
If he chooses one code:
P = 1 / 720 = 0.138 %
Probably, 1/720 is the best way to write the answer since it shows what it means.
--Answer--
The number is 8.
We verify:
x + 12 = 20
x = 20 - 12
x = 8

I hope it helps you :)
