The number of Oreos and cookies in a box is in the ratio 4:9. Zane bought each Oreo at $2 and each cookie at $3. How much more money did Zane spend on buying the cookies than buying the Oreos if the total number of items in the box is 65?
The total ratio representing the number of cookies and Oreos that Zack bought is 4+9=<<4+9=13>>13
The fraction representing the number of Oreos Zane bought is 4/13, and since the total number of items in the box is 65, Zane bought 4/13*65=<<4/13*65=20>>20 Oreos.
If Zane bought 20 Oreos at $2 each, the total cost of buying Oreos is $2*20=$<<20*2=40>>40
Since the total number of items in the box is 65, and there are 20 Oreos in the box, the number of cookies in the box is 65-20=<<65-20=45>>45
The cost of buying the cookies at $3 each is 45*$3=$<<45*3=135>>135
If the Oreos cost $40 to buy, Zane used $135-$40=$95 more to buy Cookies than Oreos.
