Answer:
$820
Step-by-step explanation:
D= Diamond Ring
S= Silver Ring
2D + 4S = 1880
D + S = 880
D = 880 - S
4S + 2(880 - S) = 1880
4S + 1760 - 2S = 1880
2S + 1760 = 1880
2S = 120
S = 60
880 - 60 = 820.
Answer:
4 pints
Step-by-step explanation:
The conversion from pint to ounce is:
1 pint = 16 ounces.
The teacher collected 19 pints, that is, 19*16 = 304 ounces of lake water.
If there are 60 students, and each of them use 4 ounces, the total of lake water used is 60*4 = 240 ounces.
So, the amount of lake water left is 304-240 = 64 ounces, that is, 64/16 = 4 pints.
