Rita started the day with R apps. Then she deleted 5 apps and still had twice as many apps as Cora. If Cora has 36 apps write an equation that shows the number of apps each girl has.

Answer 1

R-5=2C=2(36)=72

R-5=72

R=72+5=77

Rita has 77, Cora has 36

one equation is R-5=2C or R=2C+5

and for Cora 2C=R-5 or C=(R-5)/2
