Answer:
Earl should order 76 yellow paper reams and 24 white paper reams.
Step-by-step explanation:
This problem can be computed as system of equations.
I will say that x is the number of yellow paper reams and that y is the number of white paper reams.
Earl will order 100 reams in total, so
x + y = 100
He has a budget of $484, so this is what he is going to spend. Each yellow paper ream(x) costs $4.00 and each white paper ream costs $7.50, so we know that
4x + 7.5y = 484
To know how many reams of each color should he order, we need to solve the following system of equations
1) x + y = 100
2) 4x + 7.5y = 484
I am going to write x as a function of y in equation 1), and then replace it in equation 2).
x = 100-y
Now replacing in equation 2)
4(100-y) + 7.5y = 484
400 - 4y + 7.5y = 484
3.5y = 84
y = 24.
Returning to equation 1)
x = 100-y = 100-24 = 76
So, Earl should order 76 yellow paper reams and 24 white paper reams.
Answer:
120 degrees the sum of all angle is 720 degrees In the above
Answer:
225 seconds
Step-by-step explanation:
First,
1km = 1000 meter
This means,
0.9 km = 900 meter
Second, to find the time taken,
0.25 x 900 = 225
Therefore,
225 seconds
