Answer:
Rita: r - 5= 2c, or r - 5= 2(36), or r - 5 = 72
Cora: (r - 5)/2 = 36
Explanation:
- Rita had r apps (let r = Rita original apps)
- She deleted 5 of them so r-5
- She now has twice the number of apps as Cora so r-5 = 2c (let c = Cora's total apps)
- Cora's total apps are 36 so Rita's equation is r-5= 2(36) which means Rita equation for her number of apps is r-5= 72.
- As for Cora her equation is c= 36 but in relation to Rita's number of apps it's (r-5)/2 = 36
