14. In Lab 7.3 we were given a set of N rate table cards containing Killowatt
hours used, a constant and the rate for that rate step. The layout of
the rate cards is

Card Columns Description

1-4 KWH used (XXXX,)

5-8 Constant (XX,XX)

9-12 Rate (,XXXX)
The number N<20 of cards in the rate table is punched in columns l and 2
of a parameter card that precedes the table deck. An array NUM is used
to count the number of bills computed in each rate step.

(9 pts) a) Write the FORTRAN statements reguired to begin this program, read

the table cards and establish the table composed of the arrays USE,
(Killowatt hours used), C (Constant) and R(Rate), and to initialize
the array NUM to zero.

(7 pts) b) In Lab 7.3 we read a card from which we computed the usage U. Write
the FORTRAN statements reguired to look up the usage U in the rate
table and calculate the bill BILL by adding the constant from the table
to the usage U times the rate from the table. Also, add I to the
corresponding element of the array NUM to count the bills in that
rate step.
