Question 154821
 Henry sold 120 magazine subscriptions in x+2 days. If he sold at the same rate for another week, then how many magazines did he sell in the extra week?
:
The no. of mags sold per day:
{{{120/((x+2))}}}
:
No. of mags sold in 7 days (the extra week):
7*{{{120/((x+2))}}} = {{{840/((x+2))}}}
:
:
You can prove this to yourself, let x = 2
{{{120/4}}} = 30 mags per day
In one week: 7 * 30 = 210
:
Using our solution:
{{{840/4}}} = 210
