I really have a hard time with this question. Would you please have a look at it and explain it to me? thanks

A certain shop only sells items for a whole number of dollars and ninety-nine cents. If Mrs. Jones spent less than $50 at the shop, how many items did she buy? (1) She paid$36.72 for the items that she bought.

(2) Mrs. Jones did not spend more than $10.99 for any one item. OA is A, but how???? thanks!

should be A.

St 1: it is suff as only 28 items can be purchased.
St 2: it is not suff as we do not know how much she spent. it could be 36.72 or 36.72 + 1.99 or 36.72 + 2.99 or 36.72 + 10.99 or so on. so the number varies.

so A is fine.

I don't know if this is the right procedure, but here's what I did.

You just have to find a number that multiplied by 99 will yield 72 in its last two digits.

Since 8 is the only number that yields a 2 when multiplied by 99 in its last digits, just try until you get the one. 8 yields 7.92, not it. 18 yields 17.82, not it. 28 yields 27.72, so she must have bought 28 items.

Is this correct? Does anyone has a better way to do this?

I agree. Plus, statement B can't be true. And if I'm right, I think both statements MUST be true in the GMAT at all times. It's a matter of sufficiency, not finding which one is true, and which one isn't.
