Let x = discount rate
Equate:
$80(1-x) = $60
Solve for x:
1-x = 60/80
1-x = 3/4
x = 1 - 3/4
x = 1/4 or 0.25
x = 25%
Answer:
31.5 m^2
Step-by-step explanation:
To find the amount for 7 bags, create a proportion.
To solve for y, cross multiply numerator to denominator of each fraction.
4(y) = 18(7)
4y= 126
y= 31.5
7 bags will do 31.5 m^2
The ratio would be 2:4:6. For every 2 mice, there is 4 cats, and 6 dogs. This could be simplified to 1:2:3 by dividing all by 2.
