5. A grandfather gives $2640 to be shared to his grandchildren in the ratio of their ages. The grandchildren are 8, 10, 13 and 17 years old.
How much more does the oldest receive than the youngest?​

i think it is c, not positive though

step-by-step explanation:

15 batches are the most you can make

step-by-step explanation:

linear pair postulates

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
