Pam says she will charge 125 plus 15 an hour to paint a house. Michelle will charge $50 plus $20 per hour to paint a house. Afte
aniked [119]
Let us assume the number of hours after which the cost of Pam and Michelle will be same = x
Now let us concentrate on the information's already given in the problem.
Fixed charge taken by Pam = $125
Charge per hour taken by Pam = $15
Fixed charge taken by Michelle = $50
Charge per hour taken by Michelle = $20
Then
125 + 15x = 50 + 20x
20x - 15x = 125 - 50
5x = 75
x = 75/5
  = 15
So after 15 hours the charge taken by Pam and Michelle will be the same. I hope the procedure for doing this type of problem is clear to you.

Jayla ate 75% of the jelly beans in the bag. If she ate 24 jelly beans how many were in the bag?
maksim [4K]

Answer:

32 jelly beans were in the bag

Step-by-step explanation:

We know 75% is 3/4 and that she ate 24, so divide 24 by 3 then multiply it by 4:

24/3= 8

8 x 4 = 32

GamesOnly is having a “30% Off Everything!” sale. They have a PS4 on sale for $182. What was the original price?
Setler79 [48]

Answer:

original price = 260

Step-by-step explanation:

original price * percent off = discount

then subtract the discount

original price - discount = new price

so

original price - original price * percent off = new price

factor out the original price

original price( 1- percent off) = new price

original price = new price/ ( 1- percent off)


lets put in what we know

original price = 182/(1-.30)

original price = 182/(.7)

original price = 260

Jack can swim 3 laps in 7 minutes.<br><br> At this rate, how many laps can Jack swim in 28 minutes?
Gekata [30.6K]
Jack can swim 12 laps in 28 minutes. 28 minutes is 4 times greater than the time it took him to swim 3 laps. With 28 minutes he should therefore be able to swim 4 times as many laps. 3 times 4 equals 12
