Step-by-step explanation:
Answer:
x = 6, y = -8
Step-by-step explanation:
First we take the equations side by side and put them like this:
6x + 2y = 16
+ 2x - 2y = 32
8x = 48
Then solve for x.
x = 6
Then insert x back into either equation
2(5) - 2y = 32
10 - 2y = 32
solve for y,
y = -10
Answer:
Selling price should be $21 per unit.
Step-by-step explanation:
Cost price of manual = Fixed price + variable cost per package×Number of units sold
= 780000+19.85×1250000 = $25592500
Now we know Learning center wants a profit = $650000
Then profit = sale price - cost price
650000=sale price - 25592500
Sale price = 650000+25592500 = $26242500
This is the sale price of 1250000 units then selling price per unit should be = Total selling price/Number of units sold
= $26242500/1250000 =20.994 or $21
Selling price should be $21 per unit.
