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?

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
