Sally and Emma were hosting a bake sale for charity. They were selling apple pies for $8 and lemon squares for $7. They sold a total of 83 items and earned $624. How many of each type of baked good did they sell? Solve using an equation and using x and y variables. (PLEASE HELP I NEED THIS DONE ASAP)

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.
