The far left column represents the 10's place and the digits to the right represent the 1's place.

look at the "3" row. How many digits are greater than 2?  → 4,4,4,5,7 = 5 digits

How many digits are in the "4" row (representing ages in their 40's)? → 6 digits

How many digits are in the "5" row (representing ages in their 50's)? → 5 digits

How many digits are in the "6" row (representing ages in their 60's)? → 4 digits

How many digits are in the "7" row (representing ages in their 70's)? → 1 digit

How many customers are older than 32? 5 + 6 + 5 + 4 + 1 =  21

B

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
