Select the correct option
A) 32

5c + 10d= 460   c &gt; d   Pick an easy number to work with.   suppose c=30.   Then you have 150.   You need another 310 and that means you need d=31 which is greater than c.   Therefore, c &gt; 30.   The only answer choice where c &gt; 30 is if c = 32.   32 is the answer.
