Jessica takes an airplane to visit her parents. She pays the airline a total of $450. The cost of the ticket is $425. The airline also charges. $5 for every pound that the luggage goes over the 50 pound limit. How many pounds is Jessica's luggage over the 50 pound limit?i

5 pounds

Step-by-step explanation:

Let the pound of luggage over 5o be x

then

425 + 5x =450

or, 5x = 450-425

0r, 5x = 25

x = 5

5 Ibs

Step-by-step explanation:

So she spent a total of $450, and she had to spend $425 on the airline ticket.

So she has $25 left, but she spent $450 total so that extra $25 must be for the extra luggage. So it says $5 for every Ib. past 50. So $5 will go into $25 5 times. 5 x 5 = 25. So she has 55 Ibs of luggage so thats an extra 5 Ibs.

Hope it helps :P

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
