Given the SAS data set PRICES:

PRICES -
prodid price

K12S 5.10 producttype -

NETWORK sales -
15 returns
B132S 2.34 HARDWARE 300 10
R18KY21.29 SOFTWARE 25 5
3KL8BY 6.37 HARDWARE 125 15
DY65DW 5.60 HARDWARE 45 5
DGTY23 4.55 HARDWARE 67 2
The following SAS program is submitted:
data hware inter soft;
set prices (keep = producttype price);
if price le 5.00;
if producttype = HARDWARE then output HWARE;
else if producttype = NETWORK then output INTER;
else if producttype = SOFTWARE then output SOFT;
run;
How many observations does the HWARE data set contain?
