Let X denotes the amount Joshua paid for the pens in first place.Joshua sells a pack of pens for $3.15. $3.15 is 5% more than Joshua paid for them. So, we can write the following equation: X+5% of X=$3.15 X+5/100*X=$3.15 X+0.05*X=$3.15 1.05*X=$3.15 X=$3.15/1.05 X=3 Joshua paid 3 USD for the pack of pens. There is only one solution to the equation.
