The total number of notes is 32
<h3>The number of notes</h3>
Let the number of notes be x
$50 = x
$20 = x
$10 = x
$5 = x
Total number of notes = 4x
Let's find 'x'
50x + 20x + 10x + 5x = 680
85x = 680
x = 680/ 85
x = 8
We know that;
Total number of notes = 4x = 4 × 8 = 32 notes
Thus, the total number of notes is 32

x6+50=320
-----------------
x6=50-50=320-50
x6=270
x6/6=270/6
x=45
So this person is spending $45 a month.
A. is obviously the most easiest one, as you just have to fill it up 3 times to get 3 gallons.
The next one to measure exactly 3 gallons of water is B), because:
1) the 100-gallon barrel is more than 1 gallon, and is much more harder than 3 gallons.
2) Each person's 'palm' can hold different amounts of water, and so it can vary by the size of the palm.
So IF it cannot be (A), then your next choice is (B), as you only need 768 teaspoons for each gallon.
But, you should report this problem to the teacher, since A is obviously the best choice
The answer should be 21 if I am not mistaken
Answer: B
Step-by-step explanation: 14 1/5 - 2 5/6 =11 11/30
