The total charge would be $445.
Hope this helps!!
G=gas
w=bottle of water
8g + 2w = 29
12g + 4w = 45
I'm going to use elimination to cancel out the variable w by multiplying the first equation by -2.
-16g - 4w = -58
12g + 4w = 45
-4g = -13
/-4 /-4
g = 3.25
Now plug it into an equation, any equation.
8 (3.25) + 2w = 29
26 +2w=29
w=1.5
Now to check, plug it into both equations if you want.
12 (3.25) + 4 (1.5)=45
39 + 6=45
One bottle of water is $1.50, while one gallon of gas is $3.25.
Answer: f^-1(4)= 2 f^-1(-5)= -4 f^-1(0)= 0
Step-by-step explanation:
can see the answer its blurry
$6.25 × h = c
h = hours, c = total cost
$31.25 for 5 hours. $6.25 per hour
$50 for 8 hours. $6.25 per hour
