Answer: 18.7 mph
Step-by-step explanation:
We want a unit rate where 1 is in the denominator, so we divide top and bottom by 41.1

So, bike=b and accessories=a.
b+a=320
Since the bike is worth 7 times more than the accessories, the b would turn into 7a (because 7 times the cost of accessories is the cost of the bike).
The equation would now turn into 7a+a=320.
Solve for a.
7a+a=320
8a=320
a=40
Now that you know the cost of the accessories, you multiply that 40
by 7 to get the cost of the bike.
40(7)
280
The cost of the bike is $280.
The cost of the accessories are/is $40.
X-0.20x=5.56
Solve for x
So the original price is
X=6.95
