Question 1065526
.
A small factory planned to produce a batch of men’s shirts in 8 days. But producing 10 more shirts per day than planned, 
they finished the task one day early. How many shirts per day was the factory planning to produce?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Rate x Time = Output
At first,
{{{R[1]*8=N}}}
However with the rate increase,
{{{(R[1]+10)*7=N}}}
They both equal N so set them equal to each other,
{{{R[1]*8=(R[1]+10)7}}}
{{{8R[1]=7R[1]+70}}}
{{{R[1]=70}}}
So then,
{{{N=70*8}}}
{{{N=560}}}


<U>Answer</U>.  How many shirts per day was the factory planning to produce?  70.
