2 nickels (5 cents each)
3 dimes (10 cents each)
1 quarter (25 cents)
1 nickel, 1 dime, 1 quarter
5 + 10 + 25 = 40
2 nickels, 1 dime, 1 quarter
5(2) + 10 + 25 = 45
1 nickel, 2 dimes, 1 quarter
5 + 10(2) + 25 = 50
1 nickel, 3 dimes, 1 quarter
5 + 10(3) + 25 = 60
2 nickels, 2 dimes, 1 quarter
5(2) + 10(2) + 25 = 55
2 nickels, 3 dimes, 1 quarter
5(2) + 10(3) + 25 = 65
You can make 6 different amounts.
You could also find this by multiplying however many coins you have all together.
2 * 3 * 1 = 6
D = k + 20
j = 3k - 120
d = j
k + 20 = 3k - 120
20 + 120 = 3k - k
140 = 2k
140/2 = k
70 = k.....so Katie weighs 70 lbs
David and Johnathan each weigh 90 lbs
I believe the answer is 2.222222222
