Answer:

mean is 29.78

median is 16

Step-by-step explanation:

Mean== add up all the numbers then divide by how many numbers you added up

So 268 divided by 9= 29.7777... rounded to 29.78

Median= put the numbers in order from least to greatest and mark off one from the low end then one from the high end until you find the middle. Since there are an odd amount of numbers, there will be exactly one left in the middle,

8,9,15,15,16,18,22,25,140

Marcus has $28 to spend. He spent $3.75 to buy a notebook. He needs to save $11.25 but he wants to buy a snack. Chips cost $1.30

Alborosie

Total money Marcus has = $28

Money spent to buy a notebook = $3.75

Money left now = $28-3.75=24.25$

Money needed to be saved = $11.25

So, the amount of money Marcus can spend = $24.25-11.25=13$

Cost of a packet of chips = $1.30

The inequality to determine the maximum number of chips he can buy is:

Let the number of chips Marcus can buy = x

As he cannot spend more than $13 to buy chips so equation becomes:

$1.30x\leq 13$

Solving this we get

$x\leq 10$

Hence, Marcus can buy a maximum of 10 packs of chips and save $11.25
