Question

I need $450 to buy a bike. I only have $72. What percent of the cost of the bike have so far?

Answer 1

First, you would need to create an equation for this problem. Let x represent the unknown percentage.

`(72)/(450)` =
`(x)/(100)`

Next, you would cross multiply.
450x = 7,200

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 450.
x = 16%

You have 16% of the bike's cost.

I hope this helps!
