Answer:
The constant of proportionality is 2.50
Step-by-step explanation:
For a weight of 1 lb, the price is $2.50, so the price in dollars is related to the weight in pounds by the constant 2.50.
The constant of proportionality is 2.50 (dollars per pound).
Answer:
$2250
Step-by-step explanation:
First, find how much more Jayden will get each month by doing 2.5% of 5000, or multiplying 0.025 * 5000 = $125 per month.
Then, since Jayden is leaving it there for 18 months, you can do 125 * 18 = 2250.
The interest he will earn is $2250
Answer:(x,y)=(8,18)
Step-by-step explanation:
Given
5x-2y=4-------1
Second Equation
-2x+y=2-----2
Now multiply equation 2 by 2 and it to equation 1
5x-4x+0=8
x=8
substitute it in equation 1

36=2y
y=18
Therefore
(x,y)=(8,18)
