Hi there, since 38% of 500 is 190 and 38% represents the number of trees, I believe 190 would be the answer. Hope this helps!
I think 3x-4y-6=0
[don't KILL me if it's incorrect]
Answer:
-44.58%
Step-by-step explanation:
If I spent $83 on a coat and the next week found it for $46, how much did it change? Well 83-46 is $37 and is -$37 because that's how much money I lost. To find the percent change we divide the difference of -37 by the total 83.
-37/83= - 0.44578
To convert from a decimal to a percent, I multiply by 100.
-0.44578(100)= -44.58 rounded.
(1) 34.8 liters
(2) $63.55
Solution:
(1) There is a mistake in question. It is 42 liters.
Total gasoline a car can hold = 42 liters
Liters of gasoline filled in beginning of the week = 35.8
Liters of gasoline used during the week = 28.6
Remaining liters of gasoline in the tank = 35.8 – 28.6
= 7.2 liters
Quantity of gasoline need to buy to fill the tank completely
= Total capacity – Remaining gas in the tank
= 42 liters – 7.2 liters
= 34.8 liters
Hence Alberto need to buy 34.8 liters of gasoline to fill the tank.
Option B is the correct answer.
(2)
Shamika earns in first week = $25.75
Shamika earns in next week = $37.80
Total money Shamika have = First week earning + Second week earning
= $25.75 + $37.80
= $63.55
Don't add or subtract spending money, because the question is how much she have from these two weeks.
Hence Shamika have $63.55 from these two weeks.
