Carl bought an airline ticket from boston to denver. two weeks ago, the cost of his flight was $300. this week the same flight cost $375. what is the percent increase in the cost of the airline tickets

The percent increase in the cost of the airline tickets is 25%.

Step-by-step explanation:

1. Take the cost of Carl´s flight two weeks ago and subtract it from the cost of Carl´s flight this week:

2. Divide this obtained value by the cost of Carl´s flight two weeks ago:

3. Multiply the number obtained by one hundred to obtain the percent increase in the cost of the airline tickets:

%

Therefore the percent increase in the cost of the airline tickets is 25%.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
