求助一道GMAT数学题
At a bakery,all donuts are priced equally and all bagels are priced equally.What is the total price of 5 donuts and 3 bagels at the bakery?
(1) At the bakery,the total price of 10 donuts and 6 bagels is $12.90.
(2) At the bakery,the price of a donut is $0.15 less than the price of a bagel.
答案为什么是A不是C呢?条件(1)(2)加在一起不是可以得出donut和bagel的单价嘛?然后就可以求出he total price of 5 donuts and 3 bagels at the bakery啦?

是因为(1)alone成立所以就不考虑(1)(2)加在一起成不成立了是吧?

可以这么说,如果考虑2就绕远了。只有问题的数字变动后才需要2
