Marginal utlility problem

This is another problem that I am stuck on. This is an example that is similar to what I've been asked to do, NOT the actual question.

Consumer has a choice of goods, x and y. X is $2 and Y is $3. How much of x and y will the UT maximizing consumer purchase with an income of $17?

UNITS              MUx              MUy
1                  10                5
2                   8                4
3                   2                3
4                   2                2
