The equation for decreasing a price by 20% is
original price x 0.8 = sale price
Here, we can fill in the sale price so
original price x 0.8 = 51.44
This can be rearranged to show:
51.44 ÷ 0.8 = original price
So the original price was $64.30
Answer = B - $64.30
Answer:
Step-by-step explanation:
1) 2x -y = 1 -------1
3x - y = -6 ------2
Subtract eqn 2 from eqn 1
-x = 1--6 = 7
x = -7
Put x= -7 in eqn 1
2*-7-y = 1
-14-y = 1
- y = 15
y = -15
2) 4x +2y = 10------1
y = 4x + 2--------2
Put eqn 2 in eqn 1
4x + 2 ( 4x+ 2) = 10
4x + 8x + 4 = 10
12x = 6
x = 6/12 = 1/2
Put x = 1/2 in eqn 2
y = 4* 1/2 + 2= 2 + 2
= 4
3) 6x - y = 2------1
y = 3x + 4---------2
Put eqn 2 in eqn 1
6x - (3x +4) = 2
6x - 3x - 4 = 2
3x = 6
x = 2
y = 3*2 + 4 = 6 + 4
= 10

Hello there, this problem is just basic addition, here is what it would look like
Solve it and we get 78.21
Basically, what you will do is 540 divided by 6
When you divide that, you should get, 90 parcels.
Hope this helps! Have a good rest of your day! c:
