Carly and tom mason keep records of their expenditures. they want to know much they spend each month, on the average. their records for four months are shown below. what is their average monthly expenditure?

The average expenditure is $4586.32

Step-by-step explanation:

January: $5,678.54

February: $3,665.77

March: $4,231.98

April: $4,768.99

The average monthly expenditure is the sum of all expenditures computed/number of months

Jan+Fev+Mar+Apr/4 = 5,678.54 + 3,665.77 + $4,231.98 + $4,768.99/4 = 18,345/4 = 4586.32

So, the average expenditure is $4586.32

boxplot

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
