A hypothetical element has two main iso- topes. One has a mass of 35 amu and the other has a mass of 37 amu. If the atomic weight of this element is 35.55 amu, what is the percent abundance of the 37 amu isotope?

Let x = abundance of 35 and 1-x = abundance of 37.
Then 35x + 37(1-x) = 35.55
Solve for x and 1-x. and they will be a decimal. Multiply by 100 to convert to percent abundance. Post your work if you get stuck..
