The senior counselor is making a histogram of the yearly cost of tuition of 20 colleges. Tuition ranges from $5,000 to $51,000 a year. What would be best to count by, on the tuition axis?

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
