The local bike shop sells a bike and accessories package for $225. if the bike is worth 8 times more than the accessories, how much does the bike cost?

$200

Step-by-step explanation:

let x be the cost of accessories

let 8x be the cost of the bike

8x+x = 225

9x = 225

x = 225/9

x = 25

8x = $200

Step-by-step explanation:

1)

Bike's worth: 8a (where a=accessories)

Accessory: a

So...

8a+a=225

9a=225

a=25

So the accessory costs $25 dollars!

2)

bike + accessory=$225

We already know that the accessory costs $25.00! So we can just replace the accessory in the equation above with 25.

bike+25=225

bike= $200

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
