So I think you should set up an equation like this: 14.95x+16.88y=131.18 , x+y=8
so x=8-y, plug this into the original equation:
14.95(8-y)+16.88y=131.18
Evaluate: 119.60-14.95y+16.88y=131.18
Combine like terms: 119.60+1.93y=131.18
Subtract 119.60 from both sides. You get: 1.93y=11.58
Divide both sides by 1.93. You get y=6
Plug into second equation: x+y=8 ---> x+6=8 and solve for x. x=2
Christine bought 2 video games and 6 CDs. 14.95(2)+16.88(6)=131.18
Let's say that Bob is x and James is y
x + y = 180
x = 2y
2y + y = 180
y = 60.
James spent 60 dollars.
Answer:
C. $0.0004
Step-by-step explanation:
Cost per cubic foot is found by dividing the cost by the number of cubic feet of volume the space has. Of course, the volume is the product of the dimensions, so we have ...
cost per ft³ = $1500/((250 ft)(300 ft)(50 ft)) = 15×10²/(3.75×10⁶) $/ft³
= 4×10⁻⁴ $/ft³ = $0.0004 per cubic ft
Answer:
6x ≤ 40
x ≤ 6
Step-by-step explanation:
Assuming you mean that every time you make a product, $6 dollars comes off your limit:
6x ≤ 40
x ≤ 6.666666...
Because you cant make a fraction of a product:
x ≤ 6
