Step-by-step explanation:
Given that at a self-service gas station, 40% of customers pump regular gas, 35% pump midgrade, and 25% pump premium gas. Of those who pump regular, 30% pay at least $30. Of those who pump midgrade, 50% pay at least $30. And of those who pump premium, 60% pay at least $30.
Regular gas Midgrade Premium gas Total
Percent 40 35 25 100
atleast 30 30% 50% 60%
a) The probability that the next customer pumps premium gas and pays at least $30
=
b) the probability that the next customer pays at least $30
= P(regular and pays atleast 30%)+P(premium and pays atleast 30%)+P(midgrade and pays atleast 30%)
=
Original Price = $42
Discount = 25% ---------> 25% is discount because it says 25% <span><u />off!!!</span>
Now,
Sale price = original price - discount % of original price
= 42 - 25% of 42
= 42 - (25/100) * 42
= 42 - 0.25 * 42
= 42 - 10.5
= 31.5
So, the sale price is $31.5

Before her promotion, Mitch was receiving $40,000 per year
after tax. Since the loan payment is 4%, therefore the money that goes to the
loan is:
Loan payment = $40,000 * 0.04
Loan payment = $1,600
After her promotion, Mitch is now receiving:
New salary = $40,000
* 1.25
New salary = $50,000
Therefore the new loan payment becomes:
New loan payment = $50,000 * 0.04
New loan payment = $2,000
Therefore Mitch is paying an extra payment of:
$2,000 - $1,600 = $400
Answer: $400
