We're given the following information.
00:03
A bank teller is asked to assemble $1 sets of coins, and each set will consist of three quarters, one nickel, and two dimes.
00:26
The masses are a quarter has a mass of 5 .645 grams, a nickel has a mass of 4 .967 grams, and a dime has a mass of 2 .316 grams.
00:55
What's the maximum number of sets that can be if i have 33 .871 kilograms of quarters? i'm going to call those q.
01:08
And let's immediately change this to grams.
01:23
Well, let me do one more thing here.
01:28
Times 1 quarter q is 5 .645 grams.
01:47
Let me do my math.
01:48
We can figure out how many quarters we have.
01:52
33 .81 times 1 ,000 divided by 5 .645 equals 60 or 6 ,000 quarters.
02:08
And then if i divide that by three, i could make 2 ,000 sets from the quarter.
02:17
Okay? then for my nickel, i have one nickel, and i'm told how much nickel do i have? 10 .432 kilograms of nickels.
02:37
And again we'll do a thousand grams per kilogram and one nickel is 4 .967 grams equals 2100 nickels so that means i could make 2100 sets so so far that's my rate limiting and for my dimes i have 7 .999 kilograms of dimes and the same thing my dime was 2 .316 grams per dime...
