Question

work- Henry sold 120 magazines subscriptions in x+2 days. if he sold at the same rate for another week,then how many magazines did he sell in the exra week.
Thank you everyone for your help

Answer 1

As we don't know 'x' it is impossible to solve. We can write expressions but cannot solve them
(x + 2)days = 120
(x + 9)days = 120 + y
