Patsy had twonies, $5, $10 and $20 bills, and paid exactly $71 for her new dress. How did she do it, using the least possible number of coins and bills?

Step-by-step explanation:

To pay using the smallest number of bills and coins you have to start with the greater amount that is $ 20 x 3 bills = $ 60 + $ 10 x 1 bill = $ 70 + $ 2 x 1 bill = $ 72, and you were returned 1 $.

all it means is function 3

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
