Chapter 3.7, Problem 1CE

To determine

To write:A Basic Math program to print a chart showing a combination of nickels and dimes and finding the total value.

Answer to Problem 1CE

1 2 3 4 5 6 7 8 9 10 11 12

11 10 9 8 7 6 5 4 3 2 1 0

1 11 2 10 3 9 4 8 5 7 6 6 7 5 8 4 9 3 10 2 11 1 12 0

Explanation of Solution

Given information: As given in the question: Jane has in total 12 coins, let the nickels be ‘s’ and dimes be ‘t’.

Concept Used:

A FOR……. NEXT loop in BASIC.

Calculation:

We consecutively assume initially the coins to be a combination of nickels to be ‘s’ and dimes to be ‘t’.We input variables n, d, s and t to be zero. Further we use three FOR……. NEXT loops to show combination of nickels and dimes along with the total value. The FOR …….loop works to repeat values of coins from 1 to 12 by repeating the combination of nickels and vice versa for dimes consecutively.

PROGRAM CLS

INPUT $n=0$

INPUT $d=0$

  $\begin{array}{l}s=0\\ t=0\end{array}$

FOR $i=1$ to 12   [Finds the combination for nickels]

  $s=i+n$

NEXT i

PRINT s

END

FOR j=11to 1   [Finds the combination of dimes]

  $t=j+d$

NEXT j

PRINT t

END

FOR $k=1$ to 12   [Calculates the total value]

  $\begin{array}{l}s=s+k\\ t=12-k\end{array}$

NEXT k

PRINT s

PRINT t

PRINT k

END
