Try to solve this problem without a calculator in order to fine tune your financial skills. you are considering joining bjs discount club, and the annual fee is $45. you expect that you will save 10% on your bj purchases compared to your current "non-club" stores. how much do you have to spend at bjs in order to break even on your annual fee (i. e. save an amount equal to the fee)?

$450

Step-by-step explanation:

The break even point is the point where the amount you save is the same as the amount you have spent in the annual fee.

So Annual fee= $45

Save = x (amount spent) *0.1 (you save the 10% in every purchase)

then

$45=x*0.1=> x= 45/0.1= 450 U$S

I hope this was helpful. Have a nice day!

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
