Yes. // If one or more twenties can be given out, figure // out how many and how much is still needed. if (money >= 20) { twenties = money / 20; money %= 20; } Given money of 75, twenties is set to 3 and money is changed to 15. Do the same for 10, 5, 1, .50, .25, .10, .05, & .01 and you got a universal change program.

(1) How many 20 dollar bill(s) do I need for $75? floor(75 / 20) = 3 (2) What is the remaining amount do I need to pay? $(75 - 3 * 20) = $15 (3) How many $10 dollar bill(s) do I need for $15? floor(15 / 10) = 1 (4) What is the remaining amount do I need to pay? $(15 - 1 * 10) = $5 (5) How many $5 dollar bill(s) do I need for $5? floor(5 / 5) = 1 (6) What is the remaining amount do I need to pay? $(5 - 5) = $0 (7) [3 × $20, 1 × $10, 1 × $5]

cost = 275 array[100,50,20,10,5,1] for each value in array do count = cost modulo value if count larger than zero cost = cost - (value * count) print count on the screen end cost > value end for each value Hth, cmiiw

Copy the if statement, paste it afterwards, and change the three 20's to 10. Repeat as needed.

I just can't wrap my head around how to continue the calculation. I understand how to get the first bit, money = 75, money % 20 = 15. Now how does one continue that, do I just go on with money %10= 5 ?
