To find the expected value of your gain in each prize, subtract the price of the ticket from the prize:

If the prize is $500: $500 - $2 = $498
If the prize is $250:  $250 - $2 = 248
If the prize is $160: $160 - $2 = $73

But if you did not win any cash prize, you do not have any gain because
0 cash prize - $2 ticket = -$2 which is a loss

Could someone find the expression?
KatRina [158]

Answer:

Total earned(in dollars) =2\ t+920

Step-by-step explanation:

Given:

Michael's hourly rate working as a tutor = $12 per hour

Michael's hourly rate working as a waiter = $10 per hour

Total number of hours worked by Michael for both jobs this month = 92

Let the number of hours Michael works as a tutor this month be =t hours.

∴ Number of hours Michael works as a waiter this month will be =(92-t) hours.

Amount earned by Michael this month from tutor job

⇒\textrm{Hourly rate}\times\textrm{Number of hours worked}

⇒12\times t

⇒\$12\ t

Amount earned by Michael this month from tutor job

⇒ \textrm{Hourly rate}\times\textrm{Number of hours worked}

⇒10\times (92-t)    

⇒\$(920-10\ t)     [Using distribution]

Total amount earned by Michael from both the jobs this month in dollars can be given as

⇒\textrm{Amount earned from tutor job+Amount earned from waiter job}

⇒12\ t+(920-10\ t)

⇒12\ t+920-10\ t

⇒2\ t+920

aleksklad [387]
To obtain 58 percent of 18 multiply 18 by 0.58, because 58 percent is equal to 58/100. That said, your result rounded to two decimals is 10.44.

This answers what is 58% of 18. If you have a currency, such as in the case of 18 dollars, proceed as outlined in the example right below.
