Answer:
Step-by-step explanation:
Simultaneous Equations
2u + b = $110
4u + 3b = $268
(x2) 4u + 2b = $220
(x1) 4u + 3b = $268
<em />If both the matching coefficients are the same, we subtract equation 2 from equation 1
2b - 3b = -b
$220 - $268 = $-48
-b = -$48
b = $48
If you want to find out what a unicycle costs...
Substitute b = $48 into the first equation
2u + $48 = $110
Balance the equation, whatever happens on one side, happens on the other.
2u + $48 (-$48) = $110 (-$48)
2u = $62
2u(/2) = $62(/2)
u = $31

Answer: <u><em>
$5.00 for 1 day</em></u></h2>
Step-by-step explanation:
Unit price refers to the price of an item in one unit (one), 1 in quantity in particular. $5.00 goes in daily pricing - 1 day. While the others are pricing in multiple units.
You can solve this by algebraically as well as graphically. When I tried both ways I got:
solution is x= -2<span />
