Question 545770: how to write the equation for the problem " no name oatmeal costs 2/3 the price of the leading name brand. if the no name brand is $1.50, how much does the name brand cost"

Let the no name oatmeal be N.

Let the leading brand oatmeal be L.

Then we know from the given facts that N=%282%2F3%29%2AL

We also know the value for N, it is 1.50

So we can substitute this in our equation:

1.50=%282%2F3%29%2AL

And now we just need to solve for L to find out how much the leading brand costs!

1.50=%282%2F3%29%2AL given

4.50=2%2AL multiplied both sides by 3

2.25=L divided both sides by 2

L=2.25

So our leading brand oatmeal costs $2.25, which makes sense from our given facts.

Notice how we could have also just multiplied the no name brand price by 3/2 to get the leading brand price?

That would be a little shortcut using the properties of inverse operations!

I hope this helps! :)
