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.
