Answer:
36
Step-by-step explanation:
Let's call the # of boys and girls 5x and 3x respectively. We can write:
5x = 3x + 24
2x = 24
x = 12 so the # of girls = 12 * 3 = 36
350 divided into 20 is 170 with a remainder of 10

Answer: D) $16.77</h3>
=====================================================
Explanation:
The meter goes from 9854 to 0023. You can think of 0023 as 10023 (even though the meter only has 4 digits, so it rolls over to start over again).
So,
10023 - 9854 = 169
This means 169 kw hours of electricity are used for the month of December.
The first 100 kw hours costs $4.35
There are 169-100 = 69 kw hours left, and they cost $0.18 each, so we add on 69*0.18 = 12.42 getting 4.35 + 12.42 = 16.77
Answer:
240
Step-by-step explanation:
lets see
if we sell 100 cups of lemonade that would make 200 dollars NOT ENOUGH
if we sell 100 cups of orange juice that would make 300 TOO MUCH
meaning we have the find the right one
lets say if we sell 80 lemonade cups we would make 160 then have 20 orange juice which would make 60 and 160+60= 220 so not enough either
this means we can't have as much lemonade
lets try 75 cups of lemonade
lets say if we sell 50 lemonade cups we would make 100 then have 50 orange juice which would make 150 and 150+100= 250 so too much
lets try 55 cups of lemonade
lets say if we sell 55 lemonade cups we would make 110 then have 45 orange juice which would make 135 and 110+135= 145
sooo close
try 60
60*2-120 40*3-120
120*120= 240
The answer to your question is 38.5
