PLEASE HELP ASAP!!!

The owner of a small restaurant bought 75 kilograms of rice. Each week, the restaurant uses 4.5 kilograms of rice.

Function r gives the remaining amount of rice, in kilograms, as a function of the number of weeks, w, since the restaurant owner bought the rice.

Answer 2

75 - 4.5 w would equal r if we knew what w is, then finding r would be as easy, when i divided 75 by 4.5, it gave me 16 two / thirds, so the remainder is two/thirds of 4.5 which is 3, so r = 3 and if you wanted to find w, it is 16

Step-by-step explanation: math, it's great, but horrible at the same time
