Given :
Emily sells erasers for $2 per package and pencils for $5 per package. she sells 220 total packages and earns $695.
To Find :
The number of packages of erasers and pencils that were sold
.
Solution :
Let, number of erasers are x and pencils are y.
So, x + y = 220 ....1
Also, 2x + 5y = 695 ....2
Solving equation 1 and 2, we get :
x = 220 - 85 = 135
Therefore, the number of packages of erasers and pencils that were sold are 135 and 85 respectively.
Hence, this is the required solution.
You have to find the proportion before continuing, so you multiply the numbers you already have, which is 24, and then move on, I'm sorry if this is wrong, but I think that's how its done
2y=5x+4
y= 3x+2
2(3x+2) = 5x+4
6x +4 = 5x+4
6x-5x=4-4
x=0-----------------------> y=3x+2
y=3(0)+2 = 0+2
y=2
solution (0,2) one point c.
Answer:
The Answer is c: 4x5 + x3 + 2x2 – 3
Step-by-step explanation:
To write the function correctly, it is important to assign variables correctly and understand the situation of the problem clearly. For this, we let y the number of people and x as the number of songs played.
At x = 0 y = 567
at x = 1 y = 567 - 567(1/3)
at x = 2 y = 567 - 567(1/3)(1/3)
at x = 3 y = 567 - 567(1/3)(1/3)(1/3)
Therefore, the number of people left after x songs would be represented by the equation:
y = 567 - 567(1/3)x
y = 567 ( 1- x/3 )
