Liz has to rent a bounce house for her little cousin. When looked at the prices she wanted to compare the two. Rental #1 charges a flat fee of $1 with an additional cost of $2 for every hour. Rental #2 charges a flat fee of $3 with an additional cost of $1 for every hour.

2hours

Step-by-step explanation:

Step one:

given data

Rental #1

charges a flat fee of $1 with an additional cost of $2 for every hour

let the number of hours be x

the total charge

y= 1+2x1

Rental #2

charges a flat fee of $3 with an additional cost of $1 for every hour.

let the number of hours be x

the total charge

y= 3+1x2

equate 1 and 2

1+2x=3+x

collect like terms

1-3=x-2x

-2=-x

x=2hours

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
