MATH PROGRAMS
The computer's mathematical functions can be used for work pur-
poses,
as
well
as
for play. If you were a chef who prepared food for
banquets, you might need a computer to expand your recipes. For
instance, suppose that you are trying to figure out how many pounds
of sea scallops to buy to serve Coquilles St. Jacques at a dinner for
62
guests. Your recipe indicates that 1 1
/2
pounds of scallops feeds 5
people. The program below would tell you how many pounds to buy:

The program produces the answer (18.6 pounds of scallops), but a
calculator would achieve the same result with less work.
To
make the
program more
us
eful,
al
low a variation
in
the number of guests by
in-
serting
an
INPUT statement. Type

Run
the program several times, enteri ng a different number of guests
each time. The amount of scallops
ne
eded changes each time. For
200 guests, 60 pounds of scallops are required; for 436 guests, 130
.8
pounds. The I N
PUT
function makes the program more practical.
