This ratio can be written as 8x+5x =390
Add the variables
13x = 390
Divide by 13 to get the value of x
390/13 = 30
Chun wants to <span>reduce the weight of garbage produced to 85% of the weight produced this month.
This means that, Chun's garbage weight next month should be equal to 85% of his garbage weight this month.
Translating this into an equation, we will find that:
garbage weight next month = 85% of garbage weight this month
garbage weight next month = 0.85 * garbage weight this month
garbage weight next month = 0.85*690
garbage weight next month = 586.5 pounds
Based on the above calculations, his target weight for the garbage next month is </span>586.5 pounds
Step-by-step explanation:
I. x - y = 4 --> y = x - 4
II. x + y = 4 --> y = 4 - x
Solution is x = 4 and y = 0
