Question

Dave delivered 52 newspapers all together on Saturday and Sunday. He delivered 8 more newspapers on Sunday than on Saturday. How many newspapers did Dave deliver on Sunday?
Please show work.

Answer 1

Let x=papers on Saturday and y=papers on Sunday

First make equations for the information given to you

x+y=52   (total papers)            and              y= x+8     (he sold 8 more on Sunday)

then since you know y=x+8 then substitute it in the other equation like so

x+(x+8)=52 which means 2x+8=52 which means 2x=44 and therefore x=22

the problem however asks for sunday and not saturday, so solve for y now

y=x+8 which means y=22+8 which means y=30

He sold 30 papers on Sunday
